Bronze

932 Bearing Bronze is a high strength alloy with good wear and corrosion resistance due to its tin, iron, and zinc content. It is most commonly used for bearings, bushings, and thrust washers. 932 Bronze is not heat treatable.

954 Bearing Bronze (also known as aluminum bronze) contains at least 10% aluminum, which adds to its strength and weldability. Similar to 932 Bearing Bronze, it is commonly used for bearing and bushings.

544 Bearing Bronze (also known as phosphor bronze) offers excellent fatigue and stress-cracking resistance. The material is best utilized in designs for valves and shafts.

Design Recommendations

Min Wall Thickness：0.5 mm

Min End Mill Size：0.8 mm (0.03 in)

Min Drill Size：0.5 mm (0.02 in)

Max Part Size：1200 x 500 x 152 mm[(x,y,z] (mill) 152 x 394 mm [d,h] (lathe)

Undercuts：Square profile, full radius, dovetail profiles

Radii（Depth） ：

· Depth must not exceed 12x drill bit diameter.

· For end mills, depth must not exceed 10x drill bit diameter.

Cost Saving Tip：To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
