Brass Photochemical Etching

Because of its high durability, malleability, high melting point, and non-ferromagnetic composition, brass is used in several critical industries from heat exchangers to EMI/RFI shields.

At Elcon Precision, we have more than 50 years of experience with photochemically etching brass for our customers.

Shaping Brass with Precision: The Etching Process

Brass is an alloy made of copper and zinc. Depending on the proportions of these two natural metals, brass can maintain different chemical, electric, and mechanical properties.

Being a substitutional alloy, brass is ideal in situations where sparks should be avoided, such as in fittings and tools near explosives and flammable objects.

Like stainless steel, brass is also corrosion-resistant and great in low-friction environments.

Due to all these properties, brass is highly ideal for photochemical etching. Elcon Precision offers exceptional brass etching services that maximize the highest potential of the brass metal for your application.
