Material Notes:
Weldability = B; Stress Corrosion Cracking Resistance = B; General Corrosion Resistance = C (A = best; E = worst). General 4032 characteristics and uses: Good machinability and drilling characteristics when using single point or multi-spindle screw machines. Excellent surface finish using polycrystalline or carbide tooling. Superior wear resistance, eliminated the need for hard coat anodizing. High strength, low thermal expansion.Uses: Master brake cylinders, transmission valves, copier parts, bushings for rack and pinion steering systems, sound recording devices, bearings and hydraulic applications, forged pistons.Data supplied by the manufacturer, Alcoa.
