Tube, bushing 2.1052 - CuSn12
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a pipe and a sleeve made of bronze 2.1052 (CuSn12). The supplier guarantees the timely delivery of products to any address specified by the consumer.
Bronze grade 2.1052 (or CuSn12) belongs to the group of high-strength phosphorous bronzes, which are distinguished by high fluidity and low coefficient of linear shrinkage. These bronze alloys are produced in Europe according to DIN EN 1982. The material is capable of withstanding high loads and high sliding speed, under normal or shock loading. Good performance of the products requires good lubrication and low roughness of the mating surfaces. The minimum hardness of the shaft / other adjacent part of rotation is 300 HB. Material with good wear resistance, and resistance to corrosion processes, which are activated in salt water. In connection with the absence of nickel, the resistance of the alloy to high-temperature loading is limited.
Urgency of application
Typical parts made from bronze alloy 2.1052 (or CuSn12) are elements of industrial equipment for public catering establishments, heavy-duty bearings, gear boxes, speed reducers for metal cutting machines, valve elements, worm gears, stators, water turbine working parts for moderate and lowered slip velocities. The alloy has good resistance to sea or chlorine-containing water.
