Description
Bronze Bro5c5s5 used: for the production of castings of valves, anti-friction parts operating friction (bushing, seals, grindbox with external diameter up to 300 mm and a length of not more than 250 mm), bearings; casting parts mining and metallurgical machinery; casting parts, metallurgical engineering (anti-friction parts, fittings and other parts with surface high purity); casting parts for shipbuilding, marine engineering and instrument making; castings components pulp and paper industry.
Note
Recommended as a substitute for brass Lmcs (ЛМцС58−2-2). The coefficient of friction of bronze without lubrication 0,15, with grease — 0,0093. The maximum permissible speed is 3 m/s Maximum load capacity: static — 50 kgf/cm2, dynamic — 100 kgf/cm2 s.

Cu is the basis.
According to GOST 613-79, OST 5P.9209-82 and STP M314-95, the total content of impurities should be ≤ 1.30%. Impurities not regulated by the standard are included in the total amount of impurities. The mass fraction of nickel due to copper and the sum of impurities is not included.
According to OST 24.916.01-71 the total content of impurities should be ≤ 1.30%. The content of nickel is allowed due to the copper content.
