Powder metallurgy awards of distinction

Other powdermetals parts that gleaned an Award of Distinction. Judges handed out two Lawn & Garden/Off-Highway awards of distinction. The first went to Geneva, Ill., for left and right-hand actuator arms used in zero-turning-radius controls of commercial and residential riding lawnmowers. The PM arms are made from MPIF FC 0208-50 material and replace two six-piece assemblies. This eliminates 12 parts and related labor and assembly costs. The actuator arms incorporate a bevel gear and stop lug into a lever that controls a hydraulic system. They feature a density of 6.7 gm/cm , a tensile strength of 50 kpsi, and a hardness from 75 to 100 HR Cambellsburg, Ind., captured the second award of distinction in this category for a differential carrier gear made for Brillion, Wis. The net shape part goes in a transmission for the Ariens professional Snothro line of 8.5-hp and higher snow blowers. The design improved drive torque output by speeding up the pinion and increasing the ratio after the friction disc in the transmission. The gear enables remote locking and unlocking of the differential. The complex five-level part has density of 6.8 gm/cm , a minimum tensile strength of 75 kpsi, a transverse rupture strength of 130 kpsi, a yield strength of 90 kpsi, and a fatigue limit of 34 kpsi. Parts need secondary quenching and tempering. Janesville, Wis., won the Hardware/Appliances award of distinction for PM and MIM parts used in tactical hinge-style handcuffs made by Appleton, Wis., a law enforcement products supplier. The handcuffs use 14 PM parts processed by conventional or high-temperature sintering. Five are different designs — a lock pawl, bow, side and center links, and main links. The bow has a tensile strength of 103 kpsi, and has a large 0.090-in. radius in the areas where it touches the wearers wrist. These
