Manufacturing Operations

Engineering considerations for high-yield brass components

Brass offers excellent blanking shear and spring retention when processed with properly calibrated tooling.

1. Grain-Direction Bending

To eliminate micro-cracks on sharp bend radii, our tool room orients component strips so critical bends occur transverse to the coil rolling grain direction.

2. Semi-Automatic Riveting

We combine stamped brass contacts with steel backing plates or Hylam electrical insulation boards using dedicated riveting fixtures that control clinching pressure.

3. Tumbling Deburring

Rotary tumbling machines remove blanking edge burrs without dulling critical connector mating surfaces, ensuring smooth insertion forces in wire harnesses.

FAQ

Brass stamping frequently asked questions

Why is brass preferred over pure copper for certain electrical terminals?

While pure copper has higher electrical conductivity, brass possesses significantly higher mechanical yield strength and spring retention. This prevents contact relaxation and loose pin connections in automotive vibration environments like wiring harness connectors and fuse links.

Can you rivet brass components to other materials like steel and Hylam?

Yes. Space Auto Parts specializes in riveted sub-assemblies. On our shop floor, we operate semi-automatic riveting presses specifically set up to rivet stamped brass terminals to steel backing plates or Hylam electrical insulator boards without fracturing the brass rivet shank.

How do you avoid stress corrosion cracking (season cracking) in brass stampings?

We carefully select the appropriate brass temper (typically Half Hard or Quarter Hard) and respect minimum bend radii relative to the strip rolling grain direction. For high-stress applications, parts can undergo stress-relief annealing to neutralize residual forming stresses.

What typical brass components do you supply to automotive and electrical OEMs?

We manufacture wiring harness spade terminals, connector pins, switchgear contact brackets, brush plate rivet contacts, and instrument dial bezel brackets.
