Copper Alloy (UNS C66300) is a versatile metal alloy with copper and zinc as its primary components. This alloy is mainly used in conducting equipment, plumbing fixtures, and marine applications. However, it also has various uses in art and architecture. This blog post will discuss the composition, mechanical and physical properties, uses, corrosion resistance, heat treatment, machining, and welding of this unique and durable metal alloy.
UNS C66300 Composition
Copper Alloy UNS C66300 is commonly known as high-strength yellow brass because it has a higher zinc content than traditional yellow brass. The composition of this copper alloy is 62.5% copper (Cu), 35% zinc (Zn), 2% aluminium (Al), and 0.5% manganese (Mn). This alloy is nickel-free because it does not contain nickel, which is often responsible for causing allergies in some people.
