GPNi21A-23 is Ni based powder by air gas atomized. This unique process can bring excellent corrosion and high temperature resistant.
Glass mould is an important part for glass bottle making. Because of its lifetime has the effect for the quality and quantity for bottle . The life scan of mould is the focus of every glass mold.Pta Welding Powder for glass mould can provide a good metallurgical bonding, and good anti corrosion surface layer. Except as PTA Welding Powder, Ni21A also can be used for Thermal Spray Coating like HVOF, Arc spray etc.
Powder has low oxygen content, good surface quality and high degree of spherical.Special chemical content design and easy for welding with good flow rate for forming welding layerThe welding layer is uniform and dense, moderate hardness, high temperature resistance and oxidation resistance.
Mainly used for various cast iron material and neck ring, bottom plate of glass mold by PTA welding process. Also can be used for repairing the part of glass mold.
Note:Customized size can be provided according to the requirement of customer
