The tin-phosphorus alloy tin block is prepared by a special preparation process to prepare a phosphorus-tin alloy material. The prepared tin-phosphorus alloy tin block has a uniform structure, stable and controllable quality, and a phosphorus content of about 5%. Tin-phosphorus alloy tin block can be used as a high-efficiency antioxidant additive in the electronics industry to significantly reduce the generation of oxides, and can be used as an intermediate alloy to prepare high-phosphorus alloy materials in the preparation of metal alloy materials. Phosphor tin materials are used as anti-oxidant additives for soldering.

With the advancement of the production process, the purity of the Tin-phosphorus alloy tin block is high, because the high-purity metal tin material is mainly used.
