Materials
We don't machine everything — we machine a focused set of materials well. Running the same alloys and plastics daily means dialed-in speeds, feeds, tooling, and finishing for each one. The result is consistent dimensions, predictable lead times, and finishes that don't require a second pass.
Brass
Brass is in our DNA — it's what built our custom hardware reputation. We machine and finish brass components where appearance counts as much as the dimension: hardware, fittings, and decorative-yet-functional parts that have to look as good as they measure.
Clean chips, tight tolerances, and in-house finishing mean a brass part from B&M is ready for your assembly or showcase — not your deburring bench.
| Common grades | C360 (free-machining) · C260 (cartridge brass) · others on request |
| Typical applications | Custom hardware · architectural fittings · precision components · decorative parts |
| Finishing | Deburring · vibratory finishing · polishing — all in-house |
Aluminum
Lightweight, strong, and fast to cut — aluminum and titanium are the workhorses for prototype and production parts alike. We mill and turn aluminum to tight tolerances with clean, anodize-ready finishes. Whether it's an aerospace prototype or a production run of precision components, the result is accurate dimensions and a finish worth handing to the next operation.
| Common grades | 6061 · 7075 · others on request |
| Typical applications | Aerospace components · structural parts · prototype and production runs |
| Finishing | Machined surface + anodize-ready · anodizing available through outside partners |
Stainless Steel
When the part has to resist corrosion or hold up in a demanding environment, stainless is the answer. We machine stainless to tight tolerances and the surface finish your application requires — whether that's a machined surface for function or a polished finish for appearance.
Stainless takes more care to machine well. We have the tooling and the process to do it right, not just fast.
| Common grades | 303 · 304 · 316 · others on request |
| Typical applications | Industrial components · pharmaceutical equipment · chemical processing · precision hardware · packaging equipment |
| Finishing | In-house deburring and polishing · passivation through outside partners |
Plastic
We machine plastic components where tight tolerances and clean finishes matter — prototype parts, functional components, and short-run production. The same controlled process we apply to metal applies here: correct speeds and feeds for the material, in-process inspection, and finished to your callout.
| Common materials | Delrin (acetal) · UHMW · Nylon · Polycarbonate |
| Typical applications | Wear components · fixtures · insulators · prototype parts · chemical processing |
| Volume | Prototype through short-run production |
