Properties of tin bronze metal materials:
1. Bronze mainly includes tin bronze, beryllium bronze, aluminum bronze, silicon bronze, etc. The hardness varies greatly depending on the composition and heat treatment process; the hardness of steel is related to the content of carbon and alloying elements and the heat treatment state, and there is a big difference. It is not easy to compare whether bronze or steel is harder, because there is no specific composition and processing technology. Generally speaking, steel is harder than bronze.
2. The early bronze swords mostly refer to cast tin bronzes, namely copper and tin alloys (about 20% tin content), and their hardness is about HRC25. Ancient sword steel is usually made of high-carbon steel, and its hardness is usually HRC45 or higher.
