| These elements are added to enhance such mechanical properties as machinability, strength, and hardness. |
| Total cost of making a casting is affected by required heat treatment and by weldability and machinability. |
| Lead, tellurium and selenium are added to copper and its alloys to improve machinability. |
| Lead, selenium, tellurium and sulfur are added to copper alloys to improve machinability. |
| The most important reason for this bad machinability is the extremely low thermal conductivity of titanium alloys. |
| The aluminum alloy combines the properties of machinability, corrosion resistance, strength and brazeability. |
