Characteristics:

 This Bronze has physical characteristics for hard work and with excellent anti-friction for it high lead content (dry

lubricant). It has a tensile strength of 35000 psi and a hardness of 60 to 70 Brinell.

Recommendation:

Bearing and bushing for high speeds and heavy pressures, pumps and drivers; application requiring high resistance to

corrosion, die casting, bushings for mills, cements kilns, stamping rolling mills and compressors.
