C22000 (ASTM B36) Commercial Bronze Alloy Data Specifications
Known for years as Commercial Bronze, this alloy derives its name from its rich bronze color. More a brass than an actually bronze, C220 offers a unique set of properties that make it great for applications requiring deep drawing and resistance to corrosion including values, buttons and pen ink tubes. Its appealing color also makes it ideal for architectural applications such as hinges, doorknobs, escutcheons and kick plates.
