Aerospace machining for Foster City OEMs — flight-critical brackets, housings, and structural parts in 7075-T6, Ti-6Al-4V, and 17-4 PH stainless. AS9100-aligned process.
Foster City's Aerospace Suppliers Need More Than a Job Shop
Foster City runs one of the most demanding manufacturing corridors in California. Between Lam Research pushing semiconductor equipment tolerances and Tesla's Foster City plant running precision EV drivetrains, local suppliers already live in a world of tight specs and zero defects. Aerospace companies here expect the same discipline. RivCut machines flight-critical parts for Foster City's 15 aerospace establishments and 1,800 aerospace workers — structural brackets, avionics housings, and engine components held to ±0.0005". You get CMM reports, material certs, and full AS9100D-aligned documentation with every order.

Precision CNC Machining for Aerospace Teams
Aerospace companies in Foster City need parts that are exact, traceable, and documented. A structural bracket that's off by 0.003 inches can create an unsafe condition. We machine aluminum 7075, titanium 6Al-4V, and Inconel 718 to tolerances as tight as ±0.0005 inches. Every order ships with CMM inspection reports, material certs, and documentation your quality team can use.
Flight-Critical Materials
We source and machine aluminum 7075-T6, titanium 6Al-4V, and Inconel 718 — all with full material certs and heat lot traceability.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on critical bores and mating surfaces. Every part is CMM verified before shipping.
Full Documentation
Dimensional inspection reports, material certs, first article inspection — whatever your AS9100D-aligned quality plan requires.

Why Foster City Aerospace Teams Work With RivCut
RivCut is in Union City. That puts us less than 10 miles from Foster City's main manufacturing corridor along Foster City Boulevard and the Warm Springs district. You can drop off a raw billet in the morning and tour the first article by end of week. No freight broker. No cross-country shipping risk on a $4,000 titanium blank.
AS9100D-Aligned Documentation
Foster City aerospace suppliers often support programs with rolling delivery schedules. When a drawing revision drops on a Tuesday, you need a shop that's in the same timezone, reachable by phone, and able to re-quote the same day. That's how we operate. Pacific time, all the time.
Traceable Materials Only
We also understand Foster City's broader manufacturing culture. The city's precision standards are shaped by neighbors like Lam Research, which builds semiconductor etch equipment to sub-micron tolerances, and Bosch, which runs tight statistical process control across its Foster City operations. Aerospace work here doesn't get a pass on process discipline just because the volumes are lower. We hold our shop to the same standard.
CMM Inspection on Every Order
Every aerospace order gets a dedicated point of contact — a real person who reads your drawing notes, flags GD&T conflicts before we cut, and sends you photos before the parts ship. Your quality team gets the full documentation package without having to ask twice.
Fast Prototype Turnaround
Most prototype orders ship in 5 to 7 business days. Rush available for simpler parts — tell us your program deadline.
