Magnesium Aluminum Hardeners Line of Alloys

New Product

KB Alloys, LLC. introduces a new formulation to its magnesium aluminum hardeners line of alloys. By raising the concentration of magnesium from the traditional 25% and 50% levels the new formulation takes advantage of the traditional benefits associated with the use of a master alloy, while the higher composition rivals the economics of alloying with pure magnesium through the benefits of better recoveries, improved through-put and cleaner melts.

The new product is exclusive to KBAlloys, Inc. and comes in a variety of sizes and forms to suit the needs of a wide range of customer applications. The 3.5 ounce button is designed for small furnace alloying or "touch-up" for larger additions. The waffle and slab ingots provide a convenient alloying method for medium to large furnace additions. All shapes are produced under an ISO registered process to insure consistent chemical composition, ingot weight control and metallurgical cleanliness.

The product is designed to benefit the experienced alloyer of magnesium but can make the inexperienced or infrequent user of magnesium achieve the consistent results of the more experi- enced operator. Because the density is greater than that of pure magnesium (2.0 g/cc vs. 1.7 g/cc) the 68% Mg-Al alloy has less tendency to float and burn-off. Less burn-off means fewer oxides, better recoveries and cleaner melts. With its low melting temperature (437 C/ 819 F) the 68% Mg-AL ingot melts before it can resurface and burn-off. This is a common problem of the less dense slower melting pure magnesium which has a higher melting point (650 C).
