Decorative Applications of Metal Powders


Cold Cast Objects

In the same way that copper and tin powders are mixed with paints to produce metallic finishes and coatings, this same approach can be applied to making three-dimensional objects.  Normally in casting a metal or some alloy is heated to its melting point, which is commonly hundreds of degrees Celsius, and the molten mixture is cast into a mold to form a three-dimensional object.  In cold-casting, the metal or alloy, in powder form, is blended into a clear resin.  This metal-resin mixture is cast, normally at or close to room temperature, and the curing or hardening action of the resin is responsible for creating a solid structure.  Cold casting is normally used in situations where the finished article does not require the high durability as that of an authentic metal cast object.

Glassware – Because of their corrosion resistant nature and ability to be applied by various methods such as thermal spray or with mixed clear resin blends, copper and bronze powders are a popular choice for use as decorative rims and intricate designs on stemware.   

 

Colored Surfaces 

Copper, tin, and bronze alloys are cost-effective pigment used to produce a durable metallic finish on a number of surfaces.  Because they can easily be blended into paint formulations and also direct applied by thermal and cold spray techniques, these metal powders are well suited for diverse applications.


Jewellery

Copper, tin, and bronze alloys are a popular substrate used in the fabrication of costume jewellry because these low cost metals are malleable, corrosion resistance, and possess a lustrous finish.   


Cosmetics Packaging

Copper and tin powders are employed in the fabrication of cosmetic packaging due to many of the same reasons they are used in any number of decorative applications.  These metal powders are relatively low cost, low toxicity, and can be coated onto the packaging surface by a number of methods which can accommodate plastic, glass, or metal substrates.  These metallic finishes produced from these pigments are often viewed with a high aesthetic value.  Also, they are corrosion resistance and can maintain their appearance for very long durations of time.
