Red Metals Copper, brass, and bronze alloys are non-ferrous metals with excellent electrical and thermal confictiity.
Copper is a soft and malleable (due to low hardness) that is a good conductor of heat and electricity. Pure copper is mainly used for heat and electrical transfer applications, as most alloy additions detrimentally affect copper’s conductivity properties.
Brass is an alloy of copper and zinc. The proportions of zinc and copper can be varied to create a range of brasses with varying properties. Brasses set the standard by which the machinability of other materials is judged and do not become brittle at low temperatures like mild steel. Brass has excellent thermal conductivity and is a first choice for heat exchangers.
Bronze is an alloy of copper and usually tin as the main additive that is much harder and more brittle than brass. The term “bronze” is sometimes used interchangeably for different types of copper alloys, but the most common typically refers to a mix of about 90% copper and 10% tin in its “pure” form. Common additives to bronze include phosphorous to harden bronze and lead to make bronze more cast able. It creates little friction and does not spark, making it ideal for metal on metal contact applications.
