1. The content of alloying elements is different. Tin bronze contains more tin than phosphor bronze. There are many different brands of tin bronze and phosphor bronze. Replacement depends on the specific situation, use environment, mechanical properties, etc. many factors to consider
2. Tin bronze: The tin content is generally between 3-14%, and it is mainly used to manufacture elastic components and wear-resistant parts.
Phosphor Bronze: A small amount of phosphorus is added to tin bronze to increase the strength and hardness of the alloy. It has excellent corrosion resistance and wear resistance, and can improve wear resistance, hardness, fluidity and processability.
3. Tin bronze is a dark color of copper, tin and lead alloy, the color is yellow to green, and phosphor bronze is yellow to red. Bronze is the earliest alloy in the history of metal casting. The addition of tin or lead to pure copper (copper) has special importance and historical significance. Bronze is the name of modern people. In ancient times, bronze was yellow and red, but after being buried in the soil, the color was oxidized and turned gray. It's called bronze. Compared with pure copper (red copper), bronze has high strength and low melting point (the melting point of 25% tin-melted bronze will drop to 800°C, and the melting point of pure copper (red copper) is 1083°C). Bronze has good castability, wear resistance and stable chemical properties. After the invention of bronze, it became popular immediately. Since then, human history has entered a new stage - the Bronze Age.
