Raw Materials FOR SALE at Weld Systems Integrators
Copper and Resistance Welding Alloys, Refractory Metal Compositions (Elkonite®, Elkon® and Anviloy®)
Raw materials including copper and copper-based alloys, and refractory metal compositions including Elkonite® and Elkon® are available from Weld Systems Integrators. We are a distributor of raw materials that can be used to manufacture resistance welding consumables, tools and accessories. In addition, raw materials can be used to build fasteners, including electrodes, seam welding wheels, nuts and studs.
RWMA Class 1 – Copper-Zirconium and Copper-Cadmium: Electrodes for welding aluminum alloys, magnesium alloys, coated materials, brass and bronzes. Can be used for both spot and seam welding.
RWMA Class 2 – Copper-Chromium and Zirconium: These materials are stronger than Class 1 materials, have slightly lower conductivity. They are used for spot and seam welding of cold and hot rolled steel, stainless steel and low conductivity brass and bronze. They are also used as flash welding dies, and as electrodes for the welding of galvanized steel and other coated materials.
RWMA Class 3 – Copper-Nickel-Silicon-Chromium and Copper-Nickel-Beryllium: Their high hardness makes them ideal for electrodes for spot and seam welding of high resistance materials such as stainless steels, nichrome, inconel, and monel metal. As a casting, they are used for flash, butt and projection welding electrodes and fixtures. Other uses are welding gun components, seam welding bearing and other current carrying structural parts.
RWMA Class 4 – Copper-Beryllium: Electrodes material for flash, upset-butt and projection welding applications where pressures are extremely high and wear is severe, but where heat is not excessive. They are used frequently in the form of inserts and facings. They may also be used for seam welding bushings.
RWMA Class 20 – Copper-Aluminum: Aluminum oxide has exceptional resistance to deformation when welding and it is highly recommended for weld caps when welding coated and galvanized steels. It allows a stable start-up and generally outlasts other cap material when welding parameters are not carefully controlled.
Elkonite®, Elkon® and Anviloy®
Stronger, generally harder, and having less conductivity, the refractory metal compositions include copper-tungsten (Classes 10-11), tungsten (Class 13) and molybdenum (Class 14) alloys.
Elkonite® is used to identify a group of metal compositions whose elements consist of the refractory metals tungsten-copper and copper-alloy, molybdenum, nickel, iron and tungsten carbide. Combinations of these elements produce dense, hard metals of superior wear resistance and strength at elevated temperatures, coupled with good thermal and electrical conductivity.
The mechanical and physical properties of the Elkonite materials make them particularly suitable as the die inserts and facings for volume projection welding, flash and butt welding, electrical upsetting, electroforging and mash welding applications. Furthermore, Elkonite is available heat treated for added hardness.
Elkon® 100W is extremely hard and its ductility is relatively low. It cannot be machined but may be ground to the required shape. It does not alloy appreciably with nonferrous materials and is used for cross-wire welding of metals such as copper and brass. It is also used for electrobrazing electrode material and for some electrical upsetting operations.
Elkon® 100M is used principally for electrobrazing electrode material and for cross-wire welding of nonferrous metals. It is not as hard as Elkon 100W material and may be machined or drilled to fit the parts to be joined. A typical application of this material, as an electrode, is the welding or brazing of braided or solid copper conductors to ferrous or nonferrous terminals, lugs or fittings.
Anviloy® 1150 is a machinable tungsten-based material. It was developed primarily for die-casting, aluminum permanent molding, and for difficult extrusion dies. Anviloy 1150 is a material with a low coefficient of thermal expansion, good thermal conductivity, and good material properties at elevated temperatures that combine for superior performance in a variety of applications. This unusual combination of properties results in a material with less thermal fatigue in the casting die or extrusion die.
RWMA CLASS 10 – Tungsten 55% – Copper 45%: Suited for facings and inserts for projection welding electrodes and flash and butt welding electrodes. It is recommended where (relatively) high electrical conductivity and some degree of malleability is desired.
RWMA CLASS 11 – Tungsten 75% – Copper 25%: Suited to similar applications as Class 10, and for facing on electrode forming electrodes. It is harder than Class 10, and is for general use in projection welding electrodes.
RWMA CLASS 12 – Tungsten 80% – Copper 20%: Suited for electro-forming and electro-forging facings, and for electrode facings used to upset studs and rivets. A material for heavy-duty projection welding electrodes.
RWMA CLASS 13 (pure Tungsten) and RWMA CLASS 14 (pure Molybdenum): Primarily for welding or electro-brazing non-ferrous metals having relatively high electrical conductivity. They are suited to cross-wire welding of copper and brass, and for welding copper wire braid to brass or bronze terminals. Special set-ups and procedures are required.
