Grain Refiners – AMG

Grain Refiners with a number of different titanium-to-boron, titanium-to-carbon or titanium-to-aluminium ratios are available to accommodate special conditions which may exist in the user’s plant. In selecting the proper aluminum grain refiner alloy, the user must take into consideration conditions such as the alloy to be treated, the quantity of recycle or secondary aluminum used, the desired grain size in the

AMG Aluminum – The Global Leader In Aluminum

Casthouse Grain Refining. In casthouse applications, the control of grain size is absoluy essential in maintaining product consistency and quality, in reducing costs and maintaining high levels of productivity. The controlled addition of AMG Aluminum’s titanium boron aluminium TiBAl™ grain refiners to molten aluminium releases nucleant particles that promote equiaxed, fine grain structure

Aluminum Foundry Metal Grain Refiner (TiBor) Modifier

With a few rare exceptions, it would be hard to overdo it, so just add 1 rod of each if you are melting less that 30 pounds per melt. With a small melt, add both the TiBor and Strontium rods as soon as all the metal has melted, and gently stir, skim and pour. hojpoj. 01-14-2010, 02:08

(PDF) Influence Of Titanium To Boron Ratio On The Ability

In order to improve the effectiveness and stability AlTiB grain refiners for cast Al-Si alloys, the present study investigated the grain refinement of cast Al-Si alloys using an in-situ integrated

Grain Refinement Of Aluminum Casting Alloys - PDF Free

Results from three early studies of grain refinement in high purity aluminum are shown in Figure 6 [9]. The best refinement was obtained when the Ti added was more than 0.15%, the solubility limit of TiAl 3 in

Happiness Is. | The Home

Jun 07, 2021  Typical foundry Aluminum casting alloys (engine blocks, heads, transmission cases, pistons, wheels, other cast scrap) contain 5 to 12% Silicon. A grain refiner promotes a smaller grain size even in a slow cooled casting. add both the TiBor and Strontium rods as soon as all the metal has melted, and gently stir, skim and pour.

Master Alloys – AMG

Aluminum’s mechanical and physical properties are enhanced with the use of alloying elements. These alloying elements are commonly referred to as hardeners. Aluminum-based master alloys which contain the hardener elements in high concentrations, provide a convenient and economical way to add them to aluminum to achieve desired
