Brass C35300 Machined Parts Brass CNC Machining CNC Turning

3Q MACHINING has good experience for machining quality parts from Brass C35300 alloy. We can machine any complex parts on our CNC lathe/milling machines and CNC turning centers.

Brass C35300 alloy is a high leaded brass, ideal for parts that require strength, corrosion and wear resistance, and excellent machinability. It is well suited for parts with knurling or threading, as well as moving parts that are subject to frictional forces. 

Brass C35300 is not ideal for welding or hot working, but is excellent for soldering and possesses better formability than Brass 360. Brass 353 can be annealed.

Due to brass 353’s excellent machinability and the high return value of scrap, the net cost of machining brass is competitive with steel.

Brass C35300 Applications

UNS C35300 brass alloys are used in screw machine products for peening, thread rolling, crimping, and knurling purposes. They are also used in the following applications:

    • Watch
    • Hose fittings
    • Bicycle spoke nipples
    • Clock and lock parts
    • Plumbing valve components

Brazing, soldering, and butt welding are most commonly used methods for welding the UNS C35300 brass alloys. Seam welding, gas shielded arc welding, oxyacetylene welding, coated metal arc welding, and spot welding methods are not used for welding these alloys.

Hot working

UNS C35300 brass alloys have poor hot forming capacity.

Cold working

UNS C35300 brass alloys have average cold working capacity.
