    C99300 XX Minox Metal
    Incramet 800 Alloy

    Minox "XX" Metal was developed to take care of the severe stresses and high temperatures of glass manufacturing. This copper alloy exhibits excellent thermal conductivity and resistance to thermal fatigue cracking and is relatively immune to oxidation. It offers an outstanding combination of mechanical and physical properties at both room and elevated temperatures...making it the ideal material for such components as sleeve bearings operating under these conditions.

    TYPICAL USES FOR C99300 XX MINOX METAL

    • INDUSTRIAL: Glass Making Molds, Rolls for Making Plate Glass, Parts Requiring High Thermal Conductivity, Corrosion and Scaling Resistant Parts
    • MARINE: Marine Hardware
