Laser Cladding Powders

Tungsten (W) and its alloys are amongst the hardest of all metals. In addition to its hardness, tungsten possesses the highest melting point of all pure metals making it useful for many commercial and industrial applications. The major use for tungsten is in cemented carbides, also called hard metals, which have a hardness approaching that of a diamond – ideal for use in cutting applications and in wear-resistant materials.

Tungsten carbides are used primarily in the metalworking, mining, oil drilling and construction industries. Tungsten and its alloys are used in electrodes, filaments (light bulbs), wires, welding and as components in electrical, heating, lighting and the aeronautical industry.

Nickel (Ni) is a lustrous, silvery-white metal that has relatively low electrical and thermal conductivities, has strength and toughness at elevated temperatures, is easily shaped into thin wires and flat sheets and is capable of being magnetised. More than 80% of nickel production is used in alloys. When alloyed with other elements, nickel imparts toughness, strength, resistance to corrosion and various electrical, magnetic and heat resistant properties.

Our range of nickel based laser cladding powders are formulated for applications with the below requirements;
• Excellent corrosion resistance in wide range of environments.
• High temperature oxidation resistance
• Resistance to stress corrosion cracking
• Good wear resistance and high ductility.
• Typically used for repair and surfacing of similar nickel based super alloys, non-alloyed, low alloyed and high alloyed steels.
• Repair and restoration of superalloy components, including gas turbine and air frame parts.
• Additive manufacturing via laser sintering
• Excellent corrosion resistance in hot contaminated mineral acids, chlorine and chloride contaminated media.
• Resistance to strong oxidisers and wet chlorine gases, resistant to pitting, crevice corrosion and stress corrosion cracking.

Cobalt (“Co”) is a hard, lustrous metallic element with low thermal and electrical conductivity. The unique properties of cobalt and cobalt products are responsible for their extensive applications in energy storage, industrial and other areas. These characteristics include its (i) high energy density, (ii) ability to alloy and impart strength at high temperatures, and (iii) ferromagnetic properties.

Metallurgical cobalt is the second-largest cobalt consuming market and is used to produce superalloys. Superalloys consist of cobalt with other metals such as nickel and/or iron and are heat resistant, surface stable, and corrosion and oxidation resistant materials for industrial applications. Cobalt superalloys are widely used in aerospace, electricity generation, aircraft, medical, automotive, industrial gas turbines, and military-related industries. Other applications for metallurgical cobalt include hard metals and diamond tools, catalysts in oil and gas refinement, as well as pigments and other industrial uses.

Our range of cobalt based laser cladding powders are formulated for applications with the below requirements;

• Corrosion resistance
• Oxidation resistance
• Abrasive wear resistance
• High service temperature capability
• Coatings exhibit a low coefficient of friction particularly suitable where lubrication is low or nonexistent.
• High resistance galling

Iron ore is integral to the steel-making process and one of the most sought after commodities in the world. Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of ‘alloys’ which are even stronger and don’t rust easily and can be shaped into products from cars to pins, household appliances to buildings, bridges to railways, food cans to tools. In short, we rely on iron (as steel) to make almost everything we need for living in the 21st century. Today we use twenty times more iron (in the form of steel) than all other metals put together.

Iron (Fe) is one of the most abundant rock-forming elements, constituting about 5% of the Earth’s crust. It is the fourth most abundant element after oxygen, silicon and aluminium and, after aluminium, the most abundant and widely distributed metal. The Earth’s magnetic field is due to the iron (and nickel) in its core. Iron is a silver-grey metal that quickly rusts when exposed to air and water. It is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts. Iron is not usually found in pure form within rocks, instead, it is combined with oxygen in ore minerals such as hematite.
