The ordinary flanged brass bushing is a copper-zinc binary alloy. Brass with an average copper content of 62% and 59% can also be cast, called casting brass.
Bronze originally refers to copper-tin alloy, but the industry used to call copper alloys containing aluminum, silicon, lead, beryllium, manganese, etc. also bronze, so bronze includes tin bronze, aluminum bronze, aluminum bronze, beryllium bronze, silicon bronze, lead bronze, etc. Bronze is also divided into two categories: pressure-processed bronze and cast bronze.
2. the composition is different.
Tin bronze with tin as the main alloying element of copper-based alloys called tin bronze.
In order to obtain higher strength, corrosion resistance and good casting performance, special brasses are formed by adding aluminum, silicon, manganese, lead, tin and other elements to the copper-zinc alloy. Such as lead brass, tin brass, aluminum brass, silicon brass, manganese brass, etc.
