C90300 tin bronze tube mechanical properties are particularly prominent, its tensile strength up to 400MPa or more, some high-quality products can even exceed the high standard requirements of 355MPa. This level of strength is much higher than that of ordinary pure copper and some low-alloyed copper materials, making C90300 tin bronze outstanding in the working environment of large loads and high pressure. In addition, the yield strength, elongation and hardness of the alloy are also at a high level, providing a solid performance guarantee for applications under various complex working conditions.
