解説

リン青銅，青銅の一種。青銅の脱酸にリンを用いて合金の中にほとんどリンが残っていないもの，スズ10％以下の青銅に多少リンを加えてリンが残るようにしたもの，スズ10％以上の青銅に0.05～0.5％のリンを加えたものがある。前2者は展伸材として，後者は鋳物用として使用される。スズ8％，リン0.03～0.35％のリン青銅はおもに板に加工され，すぐれたばね材料として広く使われている。また，リン青銅鋳物は耐食性に加えて，硬さが大で耐摩耗性がよいので，機械部品や製紙用ロールなどに用いられる。
定義
phosphor bronze: An alloy of coppercontaining 4% to 10% of tin and0.05% to 1% of phosphorus as a deoxidizingagent. It is used particularlyfor marine purposes and where it isexposed to heavy wear, as in gearwheels.
工業用途
This, a copper-base alloys with low phosphorus content, originally called steel bronze, was 92- 8 bronze deoxidized with phosphorus and cast in an iron mold. It is now any bronze deoxidized by the addition of phosphorus to the molten metal. It may or may not contain residual phosphorus in the final state. Ordinary bronze frequently contains cuprous oxide formed by the oxidation of the copper during fusion. By the addition of phosphorus, a powerful reducing agent, a complete reduction of the oxide takes place. Phosphor bronzes have excellent mechanical and cold-working properties and low coefficient of friction, making them suitable for springs, diaphragms, bearing plates, and fasteners. In some environments, such as salt water, they are superior to copper. Uses include bearings, bushings, gear shafts, valve components, and screw-machine products.
