Stainless Steel 409 (Ferritic)

Stainless Steel 409 is a low-cost, titanium-stabilized ferritic alloy built for heat and exhaust-gas resistance, not for decorative or highly corrosive applications.

CNC

Stainless Steel 430 (Ferritic)

Stainless Steel 430 is a magnetic, chromium-only ferritic alloy offering a bright, polishable finish at lower cost than nickel-bearing grades.

CNC

Stainless Steel 420J2

Stainless Steel 420J2 is a heat-treatable martensitic alloy that offers good machinability as-milled, with the option to harden to 50–55 HRC afterward.

Pure Iron DT4

Pure Iron DT4 is an electromagnetic-grade pure iron prized for high magnetic permeability and low coercivity in DC electromagnetic components.

CNC

4J50 (FeNi50)

4J50 is a nickel-iron precision alloy with thermal expansion matched for soft-glass and ceramic sealing, plus soft-magnetic characteristics.

CNC

Kovar (4J29)

Kovar (4J29) is a nickel-cobalt-iron alloy engineered to match the thermal expansion of hard borosilicate glass and alumina ceramics for reliable, crack-free hermetic seals.
