METAL & ALLOYS POWDERS 

MWC-1037A Ni-Al 95/5 Excellent bond coat under ceramic and metal coatings. Resists temperature to the order of 1500°F. Minimum oxide inclusions and moderate corrosion resistance. Used also for thick over lays. Good for rebuilding of worn out parts. Machinable and grindable.
MWC-1087A Ni-Al-Mo Good bond strength. Mild to moderate wear resistance. Harder than MEC-1037A due to the present of small quantity of molybdenum. Good for general repair of carbon steel and alloy steel components. Machinable with good finish.
MWC-1017A Ni-Cr This is an excellent bond coat under ceramics gives dense, clean and bright coating which resists oxidation and corrosive gases. Good for hot atmosphere to 1800°F.
MWC-1047A Ni-Cr-Al Good heat and oxidation resistance under corrosive gases. Also used normally as bond coat material for thermal barrier coatings. Specially used for rebuilding of Ni and Ni-alloyed components. Thermal stability up to 1800°F.
MWC-1044A Ni-Al-Cr-Fe-Mo Self bonding material. Good wear and oxidation resistance upto 1600°F. It is machinable to good finish.
MWC-2000A Fe-Al One step, self bonding material thermal stability is upto 350°F. Cheaper than Ni-based bond coats. Can also be used for thicker coatings. Most suitable for rebuilding and reclamation of ferrous components.
MWC-2003A Ni-Cr-Fe-Si-B/Ni-Al Hard, abrasion and wear resistance coating. Thin and thick overlays are possible. Suitable for bearing areas subjected to severe friction.
MWC-2448A Fe-Al-Mo-C 80/10/1/Low One step bonding material. Good for salvage and build-up of carbon steel components. Hard coating with good abrasion resistance. Machinable to good finish. Cheaper than MEC-1087A.
MWC-2449A Fe-Al-Mo-C Same as above with more carbon. One step self bonding material. Wider hardness range achievable. Good ground finish.
MWC-1090A Cu-Al Aluminium bronze coating with low shrinkage and less oxides. Resists cavitations, fretting and low temperature wear on hard surfaces. Machinable to good ground finish.
MWC-2052A Al-Si Good corrosion resistance. Harder, denser and gives fine texture. Machinable to good ground finish.
MWC-2404A Ni-5Al Reclamation of mis-machined or worn out parts of low carbon steel, stainless steel, brass, aluminium alloys. Machine bed ways, wear rings, press fits, bearing seats, preferably as a top coat over bond coat powder MEC-1037A.
