SP-175 / NGR, NIV
Our SP-175 board is suitable for automotive light weight checking fixture and tooling mould. Low coefficient of thermal expansion in wide temperature range with uniform cell structure can be possible to apply in severe environmental circumstances. Strictly controlled hardness and density gives work-pieces good surface roughness while control of elasticity enables engineer to do precise machining. This SP-175 has widely been used in Checking Fixture, gauge and vacuum forming mold.
