A copper alloy is an alloy of primarily copper, mixed with different alloying elements that give rise to a wide range of materials having good strength, ductility, formability, machinability and electrical conductivity.
Alloys primarily of copper and tin are considered bronzes. Copper tin alloys or tin bronzes are known for their corrosion resistance. They are stronger and ductile than red and semi red brasses. They have high wear resistance and low friction coefficient against steel.
The carbon content in tool steels may range from as low as 0.1% to as high as more than 1.6%, and many are alloyed with alloying elements such as vanadium, molybdenum and chromium.
Stainless steel grade 19-9 DL is a solid solution strengthened austenitic stainless steel. This alloy is noted for its fine grain quality and stability in a wide range of temperatures. It provides good resistance to not only corrosion but also brittle failure.
Alloy steels with low carbon content in the range of 0.1-0.3% have greater weldability and formability while maintaining the strength. In these steels, the alloying elements can either form compounds or carbides instead of simply being mixed with the iron and carbon.
Stainless steel 15 – 5 PH, also known as XM-12 or UNS S15500, is a modification of 17-4 PH developed in the 1960s. It has a more refined microstructure obtained through the remelting process.
Alloy steels are steels with alloying elements other than iron and carbon. When various elements are added to these steels, they become stronger and harder than plain carbon steels. If the total amount of alloy additions accounts for less than 5%, the steel is regarded as a high alloy steel.
Alloy steels those that are added with alloying elements to achieve certain material properties. Alloying elements are added in lower quantities to increase hardenability or strength, and in larger quantities to achieve special properties like high temperature stability or corrosion resistance.
Nickel alloy 80A is a wrought, age-hardenable nickel-chromium alloy strengthened by additions of carbon, aluminum and titanium. It has high tensile and creep-rupture properties at temperatures of up to 815ºC (1500ºF), and good corrosion and oxidation resistances.
