|(WEAR RESISTANT COPPER BASE ALLOY)|
Main applications of OM alloy
・ Forming roll (OM２８Ｆ)
Forming roll for polished steel sheet, stainless steel sheet, titanium sheet, zirconium sheet, aluminum sheet and surface-treatment steel sheet.
・ Metal die (OM３３Ｆ)
Metal die of drawing process, bending process and other forming processes for kitchen appliances, automobile, home appliances, low voltage-/high voltage electric equipment parts, gas appliances, agricultural machinery parts, pressure vessel and hardware for construction works
Mechanical parts, metal die parts, etc.
The lubrication characteristics of OM alloy are much better than those of ferrous mold materials and conventional copper-base die materials. Since OM alloy has a smaller friction resistance than ferrous mold materials, both the shock line width of drawn products and the maximum punch load are small. OM alloy also has greater drawing capabilities than ferrous mold materials so that a high drawing limit ratio is applicable for both SUS304 and SPCD drawing.
As a result of investigations of the applicability of 21 types of commercially available lubricants to OM alloy, it has been found that all of the lubricants used conventionally with ferrous mold materials can be employed directly.
OM alloy provides all of the characteristics required for press mould (die) materials such as excellent lubrication and drawing properties, wear-resistance, and thermal conductivity which brings you lowest production cost and highest productivity.
Excellent lubrication properties provide steady oil films on die surfaces, and prevent such damages as burn-on and scratches on product and die surfaces, and improve productivity supported by higher drawability.
Low friction properties improve the limit of deep drawing and reduce the number of drawing processes required. This also results in low cost and high productivity.
High wear-resistance means less die repairing, and assures less production process interruption and die maintenance costs, and leads to the improvement of productivity.
Good thermal conductivity of dies prevents temperature rise of blank absorbing deformation and friction heat of blank, lowers the sectional heat gradient of the die, equalizes local die temperature and keeps die surface temperature lower. This increases the lubrication effect and improves drawability.
