American Elements supplies seamless, rolled, or extruded gold tubing in numerous standard diameters and wall thicknesses. Available in a variety of finishes, tube gold can be further processed to produce rings, washers, sleeves and sheaths for custom applications.
Thick-walled tubes are an excellent choice for some bracelet hinges. This material is also used for certain hinge-based catches.
Some hinge makers keep several sizes of thick-walled tubing on hand and rapidly draw them down to the size required when a job comes up, which saves them the cost of having to purchase an entire range of smaller sizes.
One advantage of a thick-walled tube is that it can be easily rolled on a wire rolling mill to get a taper at the end for drawing. This helps to prevent the end from twisting, as the material stretches when it’s drawn.
Another benefit is that it’s usually very easy to obtain a polished wire core for the end of the tube. The core wire is then removed at the end of drawing, reducing the amount of scrap material that has to be cut off.
CoEx tubes are a very popular cosmetic tube for personal care lines as well as for foods and many pharmaceutical products. They are available in natural (clear), opaque or a large selection of colors including pearlescent and metallic effects as well as plastic tubes with EVOH protection. They are favored by consumers because they are so easy to use and provide a convenient packaging solution.
