We can help you make the best product choice.
Wear Resistant products from Surface Engineering are available in a large variety of forms. The most common for hardsurfacing are welding electrodes, wires, bare rods, and powders. However, castings and wrought products made from the different alloys are quite popular as well. Depending on the economics and your application capabilities, the best choice for a product can be made.

Bare Rods
Cast, sintered, or tube rods for hardsurfacing are available from .045" to 1/2" diameters for Oxyacetylene or TIG (Tungsten Inert Gas) welding. The manufacturing method depends mainly on the product, diameter, and welding process required.
Product Forms
Castings
Most of the hardfacing alloys can be used to produce castings of all sizes. Castings are manufactured via Investment, Static, Sand, Shell, Ceramic, Centrifugal, and Lost Foam processes. Castings offer value when the wear resistant component is small or difficult to hardface, when the tolerance for wear is greater than the thickness capability of hardsurfacing or the labor and processing costs for manufacturing the hardfaced component exceed those of casting.
Product Forms
Electrodes
Most of the products listed in our literature are available in the form of welding electrodes. The available sizes range from 3/32" to 1/2" diameter. Some of the electrodes are manufactured by putting the allow elements into the core of a steel tube and subsequently coating the tube. Other electrodes are manufactured using a low alloy rod and extruding coating containing additional alloying elements which will produce the final chemistry for welding.

Miscellaneous Forms
Surface Engineering also provides Dental Ingots of various alloys, sizes, and shapes. Rectangle, square and round hipped rod to the saw tipping industries, ceramic and tungsten carbide tiles of various sizes and shapes, cast wear pads containing tungsten carbide in various alloy matrix', Certified Master Alloys and remits, including scrap alloys to the casting industry, and any other specialty product that may be required to meet the demands of the industry.

Powders
Powdered metal alloys, ceramics, and composites are available in virtually all size ranges for the array of application methods utilized in industry. Surface Engineering supplies both gas and water atomized powders for Spray/Fuse and PTA applications as wall as Clad, Spray Dried, Crushed, and Sintered powders for the various Thermal Spray methods. Mesh sizes are tailored to meet application equipment specifications, providing for consistent weldability, spray characteristics, and deposit quality.

Wires
Solid and Metal or Flux-Cored Wires are available from .035" to 1/8" diameter for MIG (Metal Inert Gas), TIG, Submerged Arc (SMAW), and Open-Arc welding (OAW). The alloys listed in our literature are not available in all wire forms. However, since this is a very efficient method for hardfacing, is it often a very good idea to use the available wire form for the alloy required.
Product Forms
Wrought Products
The only common hardfacing alloy available in the form of wrought plate or bare stock is the Cobalt base alloy #6. However, virtually all corrosion resistant and aerospace alloys are available in various diameter of bar stock or plate thickness.
