Copper – T2 CNC Machining
T2 copper, also known as purple copper, is a copper-silver alloy with a copper content greater than 99.9%, and it does not have specific requirements for phosphorus content. This alloy exhibits excellent electrical conductivity, with a minimum of 56 Ms/m and a resistance of ≤ 0.0178 x 10⁻⁶ Ω·m.
Mechanical Properties
Specimen Size: Thickness ≥ 0.2 mm
Tensile Strength (σb): ≥ 195 MPa
Vickers Hardness: ≤ 70 HV
Mechanical Properties Remarks: The tensile mechanical properties are measured at room temperature for strips.
Heat Treatment
Heat Processing Temperature: 900 – 1050°C
Annealing Temperature: 500 – 700°C
Recrystallization Start Temperature for Cold Work-Hardened Copper: 200 – 300°C
T2 copper is widely used in applications requiring high electrical conductivity and good mechanical properties, making it suitable for various CNC machining processes.
