FAQ

Material questions.

Match the material to your primary functional requirement: strength-to-weight (7075 aluminum, titanium, magnesium), corrosion resistance (316L, titanium, PEEK), high-temperature service (Inconel, PEEK, Ultem), electrical insulation (Delrin, PEEK, G10), cosmetic appearance (6061 + anodize, PC), or lowest cost (6061 aluminum, ABS). Our selection guide walks through the 4 key questions.

Yes. EN 10204 3.1 mill test certificates with chemical composition, mechanical properties and heat number are provided on request for all metals. These cost nothing additional and are a free add-on for aerospace, medical, and automotive orders.

Yes, typically within 3–5 business days. Specialty alloys we frequently source: Inconel 625/718, Hastelloy C-276, duplex stainless 2205/2507, nickel 200/201, magnesium AZ31/AZ91, MP35N, monel 400/K500. Engineering plastics: Vespel, Torlon, Kel-F, Peek-GF30, carbon-filled PEEK.

Al 6061-T6 is the workhorse: yield 276 MPa, excellent machinability, good corrosion resistance, weldable, anodizes beautifully. Al 7075-T6 is stronger: yield 503 MPa (80% higher), but worse corrosion resistance, more expensive (~1.8x), harder to weld. Use 6061 by default; 7075 when strength-to-weight matters (aerospace, racing, robotics).

PEEK when: continuous service above 100°C, steam autoclavable, chemically aggressive environment, implantable medical, or strength under load. Delrin (POM) when: lower cost is important, dimensional stability under humidity, self-lubricating for gears/bearings. PEEK is roughly 15–20× more expensive than Delrin — don't over-specify.
