|---|---|
| Copper, Cu | 87 |
| Tin, Sn | 12 |
| Phosphorus, P | 0.2 |
Mechanical Properties
When it comes to mechanical properties, copper casting alloys have excellent strength in both tension and compression due to their high tensile strength and yield strength. They are also highly ductile and malleable, which makes them easy to work with when forming or machining components from the material. And because they are so strong, they can easily hold their shape after being formed into complex shapes or components.
| Mechanical Properties | Metric | Imperial |
|---|---|---|
| Hardness, Brinell (500kg) | 95 | 95 |
| Tensile strength, ultimate | ≥ 345 MPa | ≥ 50000 psi |
| Tensile strength, yield | ≥ 145 MPa | ≥ 21000 psi |
| Elongation at break | ≥ 12.0 % | ≥ 12.0 % |
| Poisson’s ratio | 0.34 | 0.34 |
| Elastic modulus | 117 GPa | 16969.4 ksi |
Physical Properties
The physical properties of copper-casting alloys make them great for various industries, including automotive, aerospace, plumbing, electrical wiring, and more. The material is non-magnetic, which makes it perfect for building devices that need to function without interference from magnetic fields, such as electrical motors or generators. It’s also non-conductive, so it won’t interfere with any electrical current running through it. Furthermore, the material is very lightweight yet retains its structural integrity even when subjected to extreme temperatures or pressures.
