Main mechanical of aluminum alloy and composite-material for welding heat exchanger
| Alloy Code | temper | Tensile Strength Rm(MPa) | Yield Strength Rp0.2(Mpa) | Extend Ratio A50(%) |
| 4343 / 3003 / 4343 | O | 95-135* | ≥35* | ≥15* |
| H14 | 140-185 | ≥125 | ≥1.5 | |
| H24 | 140-185 | ≥125 | ≥3.0 | |
| H16 | 185-225 | ≥160 | ≥1.0 | |
| H18 | ≥185 | - | ≥0.5 | |
Remark:“*”in the above file means the tensile strength will be 120-150Mpa , yield strength will be ≥45Mpa , and elongation will be ≥20% if the material of TR-050 , TR-150 , TR-151,TR-156 etc . with temper O contain Cu .
Additional: We can produce special specification according to customer’s request.
