Raffir Composites is a material consisting of metal and polymers. The metal used is aluminium with its light colour, machinability and corrosion resistance, while epoxy resins are used because of their binding strength to metal. The result is a deep coloured sparkling material for beautiful handles, jewellery etc.
The material comes in a variety of colours, is easily machined and can obtain a high gloss finish after polishing. Standard safety measures should be followed while machining the materials, and inhaling dust particles should be avoided by using local exhaust ventilation and respirator. Furthermore, water grinding is recommended for easier processing and to avoid irritation from dust particles.
Raffir Fossils are genuine mammoth fossils dating back to the last ice age (10,000-40,000 BP). The most typically found remains from the prehistoric mammoths are tusks, molars and bones. We have developed a unique resin and pressure treatment for each of these.
The fossils are not petrified, but do contain natural minerals and are harder to work than non-fossil material. Raffir Mammoth Ivory is the softest of the three, and can be worked with normal machinery for processing bone and horn. Raffir Mammoth Bone is harder, but can also be processed with the same equipment. Raffir Mammoth Molar is the hardest of the three because of its inherent enamel plates. Diamond tools are recommended for this, but tools for hard steel can also be used at low process speed if diamond tools are not available. We also recommend saturating the surface of all Raffir Fossils with cyanoacrylics (Super Glue) after grinding followed by additional fine sanding and polishing for a smother and stronger result.
