NICKEL BASE POWDER

These powders include Ni-B-Si, Ni-Cr-B-Si, Ni-Cr-B-Si-P, Ni-Cr-B-Si-Cu-Mo, Ni-Cr-B-Si-W, Ni-Cr, and Ni-Cu alloys. They are used for applications demanding corrosion resistance or oxidation resistance. Under 500℃, they have excellent low-stress abrasion and adhesive wear resistance. These powders can be applied by a variety of processes, such as, oxyaccetylene spraying or overlaying, HVOF/HVAF spraying, plasma transferred arc (PTA) overlaying, plasma spraying, laser cladding, induction fusion, centrifugal casting, 3D printing and powder metallurgical processing. Key applications include valve gates, ball valve surface, valve seats, pistons, extrusion screws, barrels, glass molds, steel mill rolls, wire drawing rolls, oil pumping shafts, fan blades, screw conveyors and tungsten carbide tools.

COBALT BASE POWDER

Cobalt base alloys typically contain tungsten and carbon for strengthening. Carbon has low solid solubility in cobalt and therefore, most of it partitions in WC, W2C and M6C or other carbides. These hard phases have a strengthening effect, making such alloys maintain high hardness and strength at temperatures under 800℃. The cobalt-chromium-tungsten-carbon alloys generally have excellent properties to resist high temperature wear, oxidation and thermal fatigue.

Cobalt has a hexagonal-close-packed (hcp) crystal structure at temperatures below 417℃. Intrinsically, it has low coefficient of friction resulting in excellent wear resistance. At temperatures above 417℃, cobalt transforms from hcp to fcc (face-centered-cubic) crystal structure, thereby, generating thermal stresses. Therefore, it is recommended that in weld overlaying and spraying, the parts being coated are pre-heated to 500-600℃ to avoid cracking in the coating or overlay.

IRON BASE POWDER

Iron base powder are basically iron-carbon alloys with additions of chromium, boron and silicon. They are typically used on mechanical parts for resisting wear and weak acid corrosion under the temperature of 500℃. Even though their properties are not as good as nickel, cobalt base alloys, they are readily available and inexpensive, making them popular in less critical applications.

 

LASER CLADDING ALLOY POWDER

With the significant advancement made in laser technology, laser cladding has gained increasing acceptance. Compared to the traditional overlaying processes, it has the advantage of low distortion, low dilution, near net shape after cladding, and fine microstructure for superior properties. However, because of concentration of heat, it could cause stress cracking. Based on our understanding of the laser cladding process, we had developed a family of powders especially for laser cladding, Our customers have endorsed them unanimously

CENTRIFUGAL CASTING ALLOY POWDER

Due to the development of fiber-reinforced plastics, inorganic fillers are increasingly used in making halogen-free plastics. Making such plastics demands superior properties to resist wear and corrosion on the extruder components, especially, extrusion screws and barrels. As a result, bi-metallic barrels are increasingly used. To satisfy both the demanding requirements on the properties of the interior barrel surface and the centrifugal casting process, our company has developed a series of powders to meet the challenge. These powders are iron, nickel, cobalt base alloys as well as Ni+WC. We are the only domestic supplier of gas-atomized powders for centrifugal casting. Their low melting points, low oxygen and impurities result in porosity-free, fine-grained structures with superior wear and corrosion resistance.

CONTINUOUS CAST ROD

The company uses an advanced technology to produce continuous cast rods of cobalt and nickel base alloys. The sizes include 2.7, 3.2, 4.0, 4.8 and 8.0 mm. These alloy rods have not only chemical uniformity but also low impurities. Their weld puddles have good flow-ability desired by a variety of weld overlaying processes to make high quality and low porosity overlays. The alloy rods have smooth surface and uniform diameter for easy feeding. The length can be supplied as requested. The rods are especially suitable for oxyaccetylene and Tungsten inert gas (TIG or GTAW) welding.
