The affinity of nickel atoms (atomic number 28) for iron (atomic number 26) results in natural occurring alloys and a large number of commercial alloys. The surfaces of these metallic compounds provide a complex electron environment for catalyzing chemical reactions.[4]
Alloy C194 is a first generation high performance alloy used worldwide. C194 combines good electrical conductivity with high tensile strength, good solderability and plateability. Applications include connectors, semiconductor pins and leadframes, sockets and mass terminations.
Many of the metals used in applications are the combinations of several different types of materials. The reason for this is quite simple. Many pure metals have the unique properties we need in certain types of applications. Such as in the case of copper, this metal offers excellent corrosion resistance in saltwater environments. It also has great electrical and thermal conductivity, as it is often used in electronics and electrical cabling. Other characteristics of copper include its malleability, ductility and softness.
However, pure metals by themselves can have negative properties which will ruin the application. In the case with copper, this metal is weak. While it can be strengthened using work hardening techniques, another way to make it stronger is to add in other metals such as iron.
Like copper, iron is also malleable and ductile. It also has good conductivity and tensile strength as it can be stretched without breaking. However, iron is corrosive, as it oxidizes when in the presence of water and oxygen to form rust.
There are times when iron will be added into copper alloys to provide positive benefits. Some of the main benefits to adding iron into copper alloys is to provide increased tensile strength and corrosion resistance without impacting the conductivity that the copper alloys already possess. Types of copper alloys that may have iron added include:
Copper-Iron Alloys: Copper-iron (CuFe) master alloys offer high tensile strength, corrosion resistance and high thermal conductivity as well high electrical conductivity. This master alloy is used as a grain refiner when added into other copper alloys such as aluminum bronze and brass alloys. It typically helps to improve the mechanical properties of low alloyed coppers.
Copper-Nickel Alloys: When introduced into copper-nickel alloys, the iron can help improve the corrosion resistance and strength of the alloy. The alloy can withstand stress corrosion cracking that can occur when used in applications within moist air and steam environments, making it ideal in marine applications. Copper-nickel is commonly used to make electrical products, electronic products and marine products.
Aluminum Bronzes: This copper alloy has roughly 6% of iron added. The iron provides strength and wear resistance. This type of alloy will be typically used in marine environments and applications.
High Copper Alloys: High copper alloys are commonly used for electrical transmission applications. While they already contain a fair amount of conductivity, there may be a certain specific electrical conductivity that is required for the application. Adding other elements such as iron can change the percentage of the conductivity to allow it to meet the ratio that is desired.
When considering whether to add iron into copper alloys for applications, you need to understand the types of properties that you want the copper alloy to have, what benefits that the iron will provide, and if there will be any negative impacts to the application. Here at Belmont Metals, we provide copper-based alloys and copper master alloys in a range of compositions. Reach out to our technical team to learn more.
Iron-nickel alloy is an example of bimetallic nanostructures magnetic alloy, which receives intensive and significant attention in recent years due to its desirable superior ferromagnetic and mechanical characteristics. In this work, a unique starfish-like shape of an iron-nickel alloy with unique magnetic properties was presented using a simple, effective, high purity, and low-cost chemical reduction. There is no report on the synthesis of such novel shape without complex precursors and/or surfactants that increase production costs and introduce impurities, so far. The synthesis of five magnetic iron-nickel alloys with varying iron to nickel molar ratios (10-50% Fe) was undertaken by simultaneously reducing Fe(II) and Ni(II) solution using hydrazine hydrate as a reducing agent in strong alkaline media for 15 min at 95-98 C. The effect of reaction volume and total metal concentration on the properties of the synthesized alloys was studied. Alloy morphology, chemical composition, crystal structure, thermal stability, and magnetic properties of synthesized iron-nickel alloys were characterized by means of SEM, TEM, EDX, XRD, DSC and VSM. ImageJ software was used to calculate the size of the synthesized alloys. A deviation from Vegard's law was recorded for iron molar ration higher than 30%., in which superstructure phase of FeNi3 was formed and the presence of defects in it, as well as the dimensional effects of nanocrystals. The saturation magnetization (Ms), coercivity (Hc), retentivity (Mr), and squareness are strongly affected by the molar ratio of iron and nickel and reaction volume as well as the total metal concentration.
Fe-SMA has some extra benefits. It is reported that the corrosion-resistance of Fe-SMA is close to that of stainless steel due to the addition of Nickel and Chromium elements [5]. This makes Fe-SMA well suited to chloride environments, e.g., coastal/offshore engineering construction. In addition, in contrast to Nitinol (another popular class of SMA) which is less easily produced in large scale because of the demanding metallurgical process [6,7,8], Fe-SMA can be mass produced with conventional metallurgical equipment [9], and, more encouragingly, the cost of the raw materials is inherently low [10]. This facilitates practical use of Fe-SMA in the civil engineering sector, where the necessary size of elements/members is often large and the budget is often controlled.
The present work provides an assessment of 3-D printed iron-manganese biodegradable scaffolds as a bone scaffold material. Iron-based alloys have been investigated due to their high strength and ability to slowly corrode. Current fabrications of Fe-based materials generate raw material which must be machined into their desired form. By using inkjet 3-D printing, a technique which generates complex, customizable parts from powders mechanically milled Fe-30Mn (wt.%) powder was directly processed into scaffolds. The 3-D printed parts maintained an open porosity of 36.3% and formed a mixed phase alloy of martensitic ε and austenitic γ phases. Electrochemical corrosion tests showed the 3-D printed Fe-Mn to desirably corrode significantly more rapidly than pure iron. The scaffolds exhibited similar tensile mechanical properties to natural bone, which may reduce the risk of stress shielding. Cell viability testing of MC3T3-E1 pre-osteoblast cells seeded directly onto the Fe-Mn scaffolds using the live/dead assay and with cells cultured in the presence of the scaffolds' degradation products demonstrated good in vitro cytocompatibility compared to tissue culture plastic. Cell infiltration into the open pores of the 3-D printed scaffolds was also observed. Based on this preliminary study, we believe that 3-D printed Fe-Mn alloy is a promising material for craniofacial biomaterial applications, and represents an opportunity for other biodegradable metals to be fabricated using this unique method.
Steel and iron are two of the most common materials used in the manufacturing industry. They are used to make a wide range of products and components. While iron and steel look similar, though, they are two unique materials with their own respective characteristics and qualities.
Our casting capabilities include steel casting, iron casting, nickel casting, copper casting, special alloy casting, iron alloy casting, abrasion resistant casting, corrosion resistant casting, corrosion resistant steel casting and corrosion resistant iron casting.
Weatherly Casting goes beyond the traditional range of steel alloys and iron. We also produce our own highly acclaimed proprietary materials to meet virtually any demand and stand up to any environment.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.
A ductile iron flanged (by mechanical joint) gate valve is designed to be the main control valve in an automatic fire sprinkler system. Ductile iron gate valves flanged by mechanical end connection allow transition of piping systems (steel to cast iron pipe).
Ductile alloy iron non-rising stem gate valves feature Class 150 raised face-end connections for easy installation and accessibility. With its ductility, these valves display higher physical properties than standard grey cast iron. In addition, stainless steel trim provides additional corrosion resistance above and beyond the standard bronze trim.
