Alcoa Deltalloy® 4032-T651 Aluminum
Categories: Metal; Nonferrous Metal; Aluminum Alloy; 4000 Series Aluminum Alloy

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.

Key Words: Aluminum 4032-T651; 4032-T651 Aluminium; UNS A94032; Alcoa, Aluminum Company of America; AA4032-T651
