Raw Materials

Eyelets can be manufactured out of 5 different kinds of raw materials. The raw material is the base material to stamp the eyelets. Depending the end product, kind of application, customers wishes, markets or prices were th e eyelets are being used, the choice of base material can be made. After the eyelets are produced , the process of treatment starts. Some treatments for metal eyelets are galvanization, painting, brushing, printing, lasering or other treatments.

BRASS:
Brass is a mix of copper and zinc. Brass is relatively a soft material and quite easy to place grommets. Brass eyelets, polished, called brass clean or raw brass can be galvanized in nickel, black, antique colors or other galvanic colors. ( see standard colors ) Property of brass is that material does not rust and can be used in a humid environment, these eyelets are possible to wash or to be used in outdoor products.                     

IRON:
Iron is a very hard metal, much cheaper than brass and more strength needed to place the grommets. Even as brass iron eyelets can be galvanized in same colors or can be painted in same colors as brass. Properties: Optically there is not a big difference but iron or steel can rust. To galvanize with nickel or zinc the eyelets will have an extra protecting, but we do not advise or guarantee to use iron eyelets in a humid environment for long time.

STAINLESS STEEL:
Stainless Steel is a mix of iron, chrome, nickel and carbon. A higher quality and durable metal with higher resistance against humid, salt and blood. Stainless steel, as well called Inox, cannot be galvanizes or painted on eyelets. Properties: Inox is a raw material, not a color. It is a stamped/punched eyelets out of stainless steel tape, deburred, cleaned and ready for sales.

ALUZINC:
Aluzinc is a patented product, quite similar as iron. Aluzinc is a kind of alloy with scrapped rest metals. Guardrails on the highway are also made from this metal alloy, that why people called this as well guardrail-steel. Properties: Very hard material, less rust than iron zinc plating, but even as iron, anti-rust cannot be guaranteed. Aluzinc can be compared with heavy galvanized iron eyelets, while zinc eyelets mostly are finished with a very thin zinc plating.

ALUMINIUM:
Aluminium is an abundant metallic chemical element which is widely used throughout the world for a wide range of products.
The element has an atomic number of 13, and classified in the poor metals, sharing the property of extreme malleability with metals like tin and lead.
Properties: Aluminium eyelets are very soft and light material, almost to easy to place grommets. The positive side of aluminium comparing iron is that it does not rust. Aluminium can also be painted in various color, but cannot have a primer before, with risk that painting comes of easily.

GENERAL:
Producing eyelets is not a lot of difference between these 5 materials, but it is very important to understand what are the differences between these materials and what is the application or use from the eyelets in the end product. We can never been claimed for customer mistakes or customers decisions for this matter. Hopefully with this small information we can only help our customers to make the right decision for his end products.
