The chemical composition of UNS C93700 (SAE 64) high-lead tin bronze alloy copper plate is mainly composed of copper (Cu) and tin (Sn) elements, and also contains a small amount of lead (Pb) elements. Among them, the content of copper is usually more than 92.5%, the content of tin is between 5.5% and 7.5%, and the content of lead is between 3% and 5%. This special chemical composition gives UNS C93700 (SAE 64) alloy copper plates excellent wear and corrosion resistance.

2. Mechanical Properties

UNS C93700 (SAE 64) high lead tin bronze alloy copper plate has good mechanical properties, its tensile strength and yield strength are higher than common copper alloys. The tensile strength of the alloy copper plate is usually between 350MPa and 450MPa, and the yield strength is between 200MPa and 250MPa. In addition, the alloy copper plate has high elongation and good plastic deformation ability.

3. Heat Treatment State

UNS C93700 (SAE 64) high lead tin bronze alloy copper plate is usually supplied in an annealed state, the heat treatment process consists of heating above the recrystallization temperature, holding for a certain period of time and then cooling with the furnace to eliminate internal stress and improve plasticity. After annealing treatment, the microstructure of the alloy copper plate becomes uniform and has good processability and weldability.

4. Hardness

The hardness of UNS C93700 (SAE 64) high lead tin bronze alloy copper plate is low, generally in the range of HB80-130. This hardness value makes the alloy copper plate easy to perform machining such as cutting and drilling.

5. Low Temperature Impact Test

UNS C93700 (SAE 64) high lead tin bronze alloy copper plate exhibits good impact toughness at low temperature, and its low temperature impact value is much higher than that of ordinary copper alloys. This makes the alloy copper plate in extremely cold areas or low temperature environment can still maintain good mechanical properties.

6. Main Application Scenarios

UNS C93700 (SAE 64) high lead tin bronze alloy copper plate is widely used in shipbuilding, petrochemical, seawater desalination, refrigeration equipment and other fields. Due to its excellent wear resistance and corrosion resistance, the alloy copper plate is often used in the manufacture of wear-resistant parts of ships, pipes and valves for seawater desalination equipment. In addition, UNS C93700 (SAE 64) alloy copper plates are also commonly used in the manufacture of contacts and conductive components for electrical equipment due to their good thermal conductivity and electrical properties.
