Seamless copper tubes according to ASTM B75 standard
Technical requirements for seamless copper tubes according to ASTM B75 standard
This specification establishes regulatory requirements for the production and quality control of seamless copper tubes with round, square, and rectangular cross-sections intended for general engineering use. EV Group China products comply with strict ASTM criteria, ensuring high precision in geometric parameters and alloy chemical composition.
The standard regulates the properties of tubes manufactured from the following copper alloy grades:
| UNS # | Copper Alloy Type |
|---|---|
| C10100 | Oxygen-free electronic copper |
| C10200 | Oxygen-free copper without residual deoxidants |
| C10300 | Oxygen-free copper with minimum phosphorus content |
| C10800 | Oxygen-free copper with low phosphorus content |
| C12000 | Phosphorus-deoxidized copper (low residual phosphorus) |
| C12200 | Phosphorus-deoxidized copper (high residual phosphorus) |
EV Group China provides technical parameters in both imperial and metric measurement systems. SI values indicated in square brackets are for reference only. To ensure engineering accuracy, it is recommended to use each measurement system independently, in accordance with project documentation.
