Freeman offers a wide range of aluminum fillers that are commonly used with epoxies and other tooling resins. Selection of the proper filler for specific applications is largely dependent on the particle size of the filler.
Aluminum Powder is typically added to resin systems in smaller concentrations (up to 10%) for appearance purposes or to increase machinablity or wear resistance. The other sized fillers are used to reduce exotherm, increase casting thickness, and reduce shrinkage. The size of the filler used depends on the size of the tool and other specific requirements.The sizes, from smallest to largest, are:
| Aluminum Powder |
0.0006" |
| Aluminum Sand (Granules) |
0.006"-.040" (100-18 mesh) |
| Aluminum Grain |
0.63" (dia.) x 0.25" to 0.375" long |
| Aluminum Spheres |
0.020"-0.074" (30-10 mesh) |
| Aluminum Shot |
0.125", 0.25", & 0.31" pellets |
