Tin Bronze Precision Castings for Engine Parts: Composition and Properties
What is Tin Bronze? Key Composition and Characteristics
Tin bronze is a copper-based alloy that contains tin as its primary alloying element. This material is widely recognized for its exceptional mechanical properties and versatility. Depending on the application, manufacturers may adjust the composition to achieve specific characteristics. For example, standard tin bronze typically contains 88-90% copper and 10-12% tin, offering enhanced strength and wear resistance. Low-tin bronze, with 5-7% tin, provides increased ductility, making it ideal for intricate designs. High-tin bronze, on the other hand, is harder and more wear-resistant, making it suitable for heavy-duty applications.
