Beryllium Free Copper (18000)
C18000
Class 3 Beryllium Free
Beryllium Free Copper (18000) meets the mechanical requirements of RWMA Class 3 Copper.
C18000 is utilized when a combination of very good mechanical strength along with moderate electrical and thermal electrical conductivity are required. C18000 is a viable substitute for C17500 and C17510 for many applications. C18000 is a heat treatable copper alloy.
| RWMA Class/(Temper) | Alloy Number | Hardness | Conductivity(%) | Tensile Strength |
|---|---|---|---|---|
| Class 3 (HT) (Beryllium Free) |
18000 | B90-94 | 48-60 | 85-100 ksi |
Hardness (17510): B20-45
TF00 or AT
This process is often referred to as Aging, Age Hardening or Heat Treating. This is the condition or temper resulting from the application of a specific time and temperature combination. This action produces an extreme strengthening effect within the material. The tensile properties change from copper-like to steel-like and the thermal and electrical properties also increase. The specific combination of time and temperature applied determines the final properties.
Hardness (17510): B92-100
TD04 or H
In Beryllium Copper this means that the material is processed like the TB00/A temper material and then gets drawn through a die to make a shape. The extra drawing through the die makes the material harder.
Hardness (17510): B78-88
TH04 or HT
In Beryllium Copper this means that the material is carefully annealed and then cold drawn to a specific size and then heat treated.
Hardness (17510): B95-102
