What's copper Alloy?
Copper Alloy is a durable, corrosion-resistant alloy primarily composed of copper and other elements like aluminum, phosphorus, tin,lead,zinc and etc
Main Copper Alloy Category
Copper alloys are primarily categorized into six major types based on their chemical composition There are over 400 different compositions, broadly grouped by their primary alloying elements

Common Used Copper Alloy Types
C86300: A high-strength material used for very heavy loads,high hardness and low speeds. It is sometimes called "high-tensile brass"
C95400/C95500: It has features for extreme strength and super corrosion resistance, especially in marine environments,underwater situation
SAE 660 (C93200):The most common general-purpose alloy. It offers a balance of wear resistance, strength, and excellent machinability
C51000/C54400: Contains a small amount of phosphorus to improve toughness and reduce friction. It is often used for springs and high-wear sliding parts.
