Overview
Eastern Alloys manufactures a comprehensive line of purpose
developed EAZALL™ coating alloys providing optimal corrosion-protection for
steel strip, shapes, and tubing and wire products. EAZALL™ brand alloys meet
the needs of the largest continuous steel strip and sheet-coating mills to
after-fabrication hot dip galvanizers to high-speed tubing and wire coaters.
New technology allows steel products to effectively compete for new structural
and architectural applications, many of which depend upon zinc coatings as an
economical means of corrosion protection. Much of this growth is a result of
new zinc coating alloys such as Galvalume™ and Galfan™ designed for specific
properties and performance.
Galvalume™ poured into sow shapes |
Eastern Alloys produces EAZALL™ coating alloys at its flagship
facility located in Maybrook, New York, in the heart of the historic Hudson
Valley region, and at Eastern Alloys of Kentucky, LLC, the company's green-site
facility in Henderson, Kentucky. The new operation, commissioned in April 2000,
is the most technologically advanced zinc alloy and recycling complex
constructed in North America. Each is ISO-9000 registered. Unique to Eastern
Alloys, Galvalume™ is manufactured in electric induction furnaces. Eastern
Alloys of Kentucky features twin 12.5 tons 1750 kW Inductotherm melters that
can produce over 50 tons per day. The use of electric induction furnaces
provides exacting chemical composition and homogeneity. Of additional interest,
Eastern Alloys is the leading manufacturer of Galfan™ in North America.
Galfan™, developed by ILZRO, differs from other coating alloys in its
composition containing rare earth metals, Cerium and Lanthanum. The principle
feature of Galfan™-coated products is the ductility of the zinc coating. As a
result, Galfan™-coated products offer creative solutions for intricately shaped
products requiring the strength and formability of steel.
Galvalume™ jumbo sows |
The Eastern Alloys product range includes coating alloys in
addition to brightener alloys for bulk-bath chemistry management. Alloys are
manufactured according to the ASTM specifications ,
or to customer-specific requirements. Steel-coating alloys are supplied in
convenient, easy-to-handle 22-pounds ingots, in ASTM strip, or custom jumbo
sows for large capacity continuous coating lines. Eastern's coating alloys can
be found at the world's leading steel coaters.
As an adjunct to its steel coating alloys, Eastern Alloys
provides dross recycling/recovery programs.
