Welcome to Hoeganaes, iron powder manufacturing. Hoeganaes specializes in powder metallurgy, and as the world’s leader in the production of ferrous powders, has been certified by DNV under the ISO/TS 16949:2002 quality management system and the ISO 14001 Environmental management system.Hoeganaes has fueled that growth with successive waves of technology which have expanded the use of prealloyed metal powders for a wide variety of applications. While the single largest application for ferrous powders is in the production of pressed and sintered parts, Hoeganaes serves a diverse set of industries, including casting, brazing, photocopy, chemical, EMI shielding and metallurgical applications. Hoeganaes commenced operations in Riverton, New Jersey in 1953.Hoeganaes creates high quality iron and steel powders, which are important raw materials in the creation of structural parts, filters and bearings. The manufacturing of these parts is accomplished through the powder metallurgy process consists of taking iron powders such as Ancorsteel 1000 and mixing them with graphite, alloys and lubricants.The metal powder mixture is then transferred to a die cavity and compacted to the desired shape. Compacting pressures for ferrous powders range from 415 to 690 MPa (30 to 50 tsi). The as-compacted part is called a “green” compact, which is sintered in a controlled atmosphere furnace in order to metallurgically bond the metal particles to each other. Some parts are used in the as-sintered condition but many are subjected to secondary operations such as sizing, tumbling, heat treatment, or machining.

Horsehead Holding Corp., together with its subsidiaries, engages in the production and sale of zinc and zinc-based products in North America. The company's products include PW zinc metal, which is used to provide a protective coating to various fabricated products, including pipe and guard rails, heat exchangers, and telecommunications towers, as well as for the production of brass; and SSHG zinc metal that is used as feed for the manufacture of high-purity zinc powder and zinc alloys. It also offers zinc oxide for the production of tire and rubber products, chemicals, ceramics, plastics, paints, lubricating oils, and pharmaceuticals. In addition, the company recycles electric arc furnace dust, a hazardous waste generated by steel mini-mills. Further, it provides special zinc powders, which are used in general chemical and metallurgical applications, as well as in friction applications, such as brake linings for automobiles; battery grade zinc powders that are used in alkaline, mercuric oxide, silver oxide, and zinc-air batteries; and copper-based powders, including brass, bronze, and nickel-silver powders, which are used in various applications comprising brazing, infiltrating, and powdered metallurgical hardware, such as lock bodies, valves, and gears. Additionally, the company offers short-line railroad service for the movement of materials. It primarily serves galvanizers and brass producers; alkaline battery industries; and manufacturers of tire and rubber products, lubricating oils, chemicals, paints, ceramics, plastics, and pharmaceuticals. The company was incorporated in 2003 and is based in Pittsburgh, Pennsylvania.

Impala Platinum Holdings Limited (Implats) is in the business of mining, refining and marketing of platinum group metals (PGMs), as well as nickel, copper and cobalt. In the 2009 financial year, Implats produced 1.7Moz of platinum (approximately 25% of global supply) and 3.4Moz of PGMs. The group employs approximately 53,000 people (including contractors) across its operations and is one of the most efficient and lowest cost primary platinum producers in the world.Impala Refining Services (IRS) uses Impala’s excess smelting and refining capacity to process the concentrate and matte produced by the various mine-to-market group operations as well as material purchased from third party companies. Toll-refining is also undertaken on behalf of other companies. Implats is one of the largest autocatalyst recyclers in the world.The company’s exploration efforts are focused on both brownfields (evaluation drilling at, or adjacent to, existing operations) and greenfields exploration. The primary focus is brownfields prospecting.
