6 W Elding Accessories Tungsten Electrodes Magnesium Aluminum
Sylvania Tungsten Vendor Code: SYL Tungsten Electrodes Magnesium Magnesium alloys are in 3 groups. They are: (1) aluminum-zinc-magnesium, (2) aluminum-magnesium and (3) manganese-magnesium. Since magnesium will absorb a number of harmful ingredients and oxidize rapidly when subjected to welding heat, TIG welding in an inert gas atmosphere is distinctly advantageous. The welding of magnesium is similar, in many respects, to the welding of aluminum. Magnesium was one of the first metals to be welded commercially by the inert-gas nonconsumable process (TIG). Accessories Welding Aluminum The use of TIG welding for aluminum has many advantages for both manual and automatic processes. Filler metal can be either wire or rod and should be compatible with the base alloy. Filler metal must be Ground Dia. Length Electrodes dry, free of oxides, grease or other foreign matter. If filler metal becomes damp, heat for 2 hours at Part No. (inches) (inches) 250˚ F before using. Although AC high-frequency stabilized current is recommended, DC reverse polarity 0407G .040 7 has been successfully used for thicknesses up to 3/32". 1167G 1/16 7 Stainless Steel Pure 3327G 3/32 7 In TIG welding of stainless steel, welding rods having the AWS-ASTM prefixes of E or ER can be used as 187G 1/8 7 filler rods. However, only bare uncoated rods should be used. Stainless steel can be welded using AC high frequency stabilized current, however, for DC straight polarity current recommendations must be increased 5327G 5/32 7 6 25%. Light gauge metal less than 1/16" thick should always be welded with DC straight polarity using 0407GL .040 7 argon gas. -
Global Tungsten & Powders Corp
GLOBAL TUNGSTEN & POWDERS CORP. Powders That Shape Your World Powders That Shape Your World Page 2 INTRODUCING GTP Global Tungsten & Powders Corp. (GTP) is headquartered in Towanda, PA in Northeastern Pennsyl- vania. GTP’s sister plant is located in Bruntal in the Czech Republic. GTP’s primary emphasis is the manufacture of tungsten and molybdenum powders with additional emphasis on other specialty products. GTP is a world leader in powder technology, high temperature metallurgy, and inorganic chemistry. GTP holds a strong global position in the development and production of inorganic phos- phors and related chemicals. In 2008, GTP was acquired by Plansee for its strategic value and core capabilities. The successful integration has expanded the Plansee Group and strengthened GTP’s core businesses and global market position. The future for GTP looks very bright as it targets new products in the Energy Exploration, Green Energy, Hard Materials, and Defense Markets. With the considerable experience and resources of the Plansee Group, GTP continues to invest in manufacturing and R&D and is well positioned for years to come. Page 3 VISION GTP’s vision is to be the leading western supplier of choice with a global footprint for refractory metal powders and specialty products by providing our customers with security of supply and continuous product improvement. MISSION GTP’s mission is to develop, manufacture and market refractory metal powders and specialty products.

Niobium As Mint Metal: Production – Properties - Processing
212 RM 21 R. Grill, A. Gnadenberger Niobium As Mint Metal: Production – Properties - Processing Robert Grill 1, Alfred Gnadenberger ² 1 Plansee Aktiengesellschaft, A-6600 Reutte, ² Münze Österreich, A-1031 Wien Summary For application as coin metal the used materials must be able to meet the demands in a wide range. This paper describes the selection criteria’s for coin metals and gives an overview about the quality and production requirements needed for special collector coins. Niobium was selected as core metal for a special 25 Euro bi-metallic coin collectors series issued by the Austrian Mint. As counterpart Silver is used as surrounding metal. A special feature of this bi-metallic coin is the use of coloured Niobium inserts. The combination of these materials with distinct different material properties, especially the deformation behaviour, and the use of the coloured Niobium insert makes an adaptation of production parameters and manufacturing philosophy necessary. Beside a general overview about the properties and applications of Niobium the paper describes the experience made during production of the bi-metallic coins. Keywords Niobium, properties, surface treatment, bi-metallic coin R. Grill, A. Gnadenberger RM 21 213 1. Introduction In the mid-term idea store of the Austrian Mint the issue of a collector’s coin on the occasion of the 700 years anniversary of the city Hall / Tyrol was foreseen. The special commemorative coin should be a continuation of the so called “25 Euro Millennium Coin” series, which was started with the material combination Ag/Ti, focusing on telecommunication and mobility published in 2000 and 2001 respectively. -
