Material Tempers & Properties
The mechanical properties of the tube are specified by its material temper designation (e.g., R250, R290).
- R250 (Half Hard): Minimum tensile strength of 250 MPa, minimum elongation of 30% (or 20% for certain conditions), and a Vickers hardness of 75-100 HV5.
- R290 (Hard): Minimum tensile strength of 290 MPa, minimum elongation of 3%, and a Vickers hardness over 100 HV5.
The designation follows the format Copper tube EN 13348 [Temper] [Diameter]x[Wall], for example: *Copper tube EN 13348 R290 15×1.0.
Property Designation Symbols (EN 1173)
The letter symbols used in property designations are defined as follows:
| Symbol | Property Definition |
|---|---|
| A | Elongation |
| B | Spring bending limit |
| G | Grain size |
| H | Hardness (Brinell for castings, Vickers for wrought products) |
| M | (as) Manufactured, i.e., without specified mechanical properties |
| R | Tensile strength (e.g., R250 = 250 MPa) |
| Y | 0.2% proof strength |
