Secondary Aluminum Solutions

HarbisonWalker International addresses the increased demand for recycled aluminum with advanced solutions that increase production efficiency and service life of your continuous high-temperature operation.

Secondary aluminum production involves aluminum metal that is not refined from aluminum oxide. It includes all aluminum made from melted ingot and all recycled scrap. Secondary aluminum casthouses use a variety of furnace types to melt and refine ingot produced in primary aluminum, as well as various scrap sources such as used beverage containers, recycled sheet, and coil trimmings.

We offer a full portfolio of firebrick linings, including our industry standard ALCOR-32® and DV-38®, as well as monolithic refractory options to perform in the most severe conditions in the secondary aluminum process.

Featured Secondary Aluminum Products

ARMORTECH 65 AL: A 65% alumina, low cement castable capable of vibration or pump casting. An advanced non-wetting package provides ultimate aluminum resistance, while still offering high hot strengths and excellent abrasion resistance. Available in coarse grain, quick-setting and fast fire, and shotcrete.

DV-38: A high fired 80% alumina, phosphate bonded brick for use in aluminum contact. This brick is ceramically bonded and delivers outstanding impact and abrasion resistance for charging zones, such as the hearth and ramp.

ALCOR-32: This premium aluminum resistant brick has a dual penetration inhibitor to offer top notch resistance to aluminum and chemical attack. Tight sizing control makes sure courses are level to provide excellent wall builders.  Also available in waffle brick for additional wall stability.

GREENGUN®-85 P PLUS: This 85% alumina phosphate bonded material offers the advantages of a gunned lining with the excellent physical properties of plastic refractories. GREENGUN is cement free and offers alkali, thermal shock and abrasion resistance. This advanced material is designed to be installed rapidly, hot or cold, to minimize turnaround time.

ARMORKAST 80 AL ADTECH®: An 80% alumina, low cement castable workhorse. Excellent aluminum resistance and strengths make this a go-to product for many aluminum contact applications. Available in coarse grain for impact and thermal cycling or self-leveling with smooth surface finish.

VERSAFLOW® Family: A robust alumino-silicate product line offering chemistries from 45-80% alumina. These economical products can offer a wide range of properties tailored to your secondary aluminum needs. All 16 products also offer the flexibility to be hand cast or pumped.

THOR® 60 ABR ADTECH®: This 60% silicon carbide based, low cement castable was designed to handle thermal cycling and abrasion needs around furnace doors and trough impact pads. Being naturally aluminum resistant, this product is a great problem solver for tough applications.
