Alloyed tin increases the corrosion resistance and strength of copper, while phosphorus increases its wear resistance and stiffness. We are using the power of our platform to aid in the mass shortage of critical supplies. The higher tin content, at 7-9%, gives Phos-Bronze C weld deposits greater hardness and higher tensile/yield strength than C518 (Phos-Bronze A). For example, if etching and inlay is part of your application, phosphor bronze may be a good balance between strength and workability, but this is dependent upon the specific alloy type and strengthening procedures. By examining the physical, chemical, and mechanical properties of phosphor bronze, this article aims to help interested designers determine if this copper alloy will be applicable to their projects. The tin increases the corrosion resistance and strength of the alloy. Tensile yield strength is a stress value that determines the point after which the material will plastically deform. Matmatch uses cookies and similar technologies to improve your experience and measure your interactions with our website. California Do Not Track Notice. When combined with its good spring characteristics, this creates an alloy that is strong and will stay strong. Aluminum bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. It is used for connector and current-carrying springs in contacts. This is because it only takes a small percentage of phosphorus, around 0.03-0.035% by weight, to imbue these alloys with unique properties such as improved flow, wear resistance, and stiffness. The results showed that the yield strength and tensile strength of C5191 phosphor bronze under high strain rates deformation increased by 32.77% and 11.07% respectively compared with quasi-static condition, the strain hardening index increases from 0.075 to 0.251, and the strength of the material strain rates sensitivity index change from 0.005 to 0.022, which presented a clear sensitive to strain … Take a look at our wide selection including BS1400 LPB10 & CuSn7PbP.
