Phosphor bronze and brass are two broad classes of copper alloys. The difference lies in the different properties and uses of ingredients.
Brass: Brass is an alloy composed of copper and zinc. If it is only composed of copper and zinc, it is called ordinary brass. If a variety of alloys composed of more than two elements are called special brass. Such as copper alloy composed of lead, tin, manganese, nickel, lead, iron, silicon. Brass has strong wear resistance.
Phosphor bronze is a bronze with tin and phosphorus as the main alloying elements. Contains 2-8% tin, 0.1-0.4% phosphorus, and the rest is copper. Main grades: China QSn10-1, QSn6.5-0.1, QSn7-0.2, QSn8-0.3, QSn4-0.3, QSn4-3, ZQSn10, ZQSn5-5-5, ZQSN6-6-3, etc.
