SP-183 / NGR
Our SP-183 as basic material for heavy weight checking fixture in automotive industry is outstanding high density tooling board. excellent CTE contributes to best work-piece without any defect and deformation and strictly controlled hardness, strength and elasticity assign uniform density distribution, tight hardness difference, anti-crack properties which might be occured during NC machining. it has widely been used for tooling jig, hammer form and the other heavy weight checking fixture.
