Aluminum

3 alloys
★ $8.99
Aluminum 6061-T6
General-purpose structural alloy. High machinability, weldable, anodizing-friendly.
Aluminum 7075-T6
Aerospace-grade, very high strength-to-weight, lower corrosion resistance vs 6061.
Aluminum 6063
Architectural extrusion alloy. Excellent surface finish & anodizing color uniformity.

Stainless Steel

4 grades
★ $8.99
Stainless Steel 303 / 304
Most common austenitic stainless. Free-machining (303), corrosion-resistant.
Stainless Steel 316
Marine-grade, superior corrosion resistance — chloride / saline environments.
Stainless Steel 316L
Low-carbon 316 — better weldability, intergranular corrosion resistance.
Stainless Steel 420 (Annealed)
Hardenable martensitic stainless. Good wear resistance — knife & mold parts.

Alloy Steel

5 grades
AISI 1045
Medium-carbon steel. Good balance of strength & machinability for shafts & gears.
40Cr (Annealed)
Chromium alloy steel. High strength, hardenable — drive parts & fasteners.
Cr12MoV (Annealed)
Cold-work tool steel. Excellent wear resistance for stamping dies.
SKD11 (Annealed)
High-chrome cold-work tool steel. Equivalent to D2 — long tool life.
DC53 (Annealed)
Improved SKD11. Higher toughness — fine-blanking dies, precision punches.

Copper

3 grades
Brass H62
Common machining brass. Good machinability and conductivity — fittings & valves.
Copper T2
Pure electrolytic copper. Excellent thermal & electrical conductivity.
Manual quote
