Materials for OEM parts

OEM metals and plastics

CNC & sheet metals

Aluminum 6061 and 7075, stainless 304/316, mild and selected tool steels, brass and copper cover most machining and sheet RFQs. Titanium and certified specialty lots are sourced after drawing review — we quote only what we can schedule.

Molding & machined plastics

ABS, PC, PC-ABS, PP, POM, nylon and acrylic are everyday resins. Glass-filled and higher-temp grades appear when duty cycle, heat or regulatory notes are on the drawing.

How to specify so quotes stick

Call out alloy temper or resin grade, color/texture, finish class and any RoHS/reach constraint in the first RFQ. Incomplete material calls are the most common reason we have to requote.
