NSM is able to reduce wall thicknesses by as much as 50%, for substantial cost savings. Design engineers can employ extrusion walls as thin as 0.030" and even less for smaller extrusions. The strength can still be maintained by use of stronger alloys offered by NSM. Extrusions can be held to a tolerance up to 200% better than previous. NSM works with a wide variety of stronger alloys, including 7000 Series. Huge Circle Size to 35" is available. ISO 9001 - 2000 certified Northern States Metals is a leader in Extrusion Technology since 1972. The company offers Turnkey Total Product solutions from value-added design, fabrication and assembly to packaging and delivery.
