What is Etching?

Etching Process

Etching is the process of corrosive removing material using etching solutions such as FeCl3.

Etching is limited within 0.0005-0.080″ (0.013 to 2.032 mm) material thickness.

Etchable metals are aluminium, brass, copper, inconel, manganese, nickel, silver, steel, stainless steel, zinc and titanium, steel, stainless steel, zinc and titanium and many others.


Chemical etching is being used in the mos
advanced industries such as:
• Aerospace, defence and space
• Automotive
• Electronis
• Medical
• Energy
• Precision engineering

Industrial applications of ethcing include
springs, pressure membranes, heat sinks,
Lex ible heating elements, RF and microwave
irc uits and components, electrical contacts, EMI /RFI shields and many others.


Etching process can offer economical alternatives to stamping, punching, laser or water jet cutting, or wire electrical discharge machining (EDM) for thin gauge precision parts.

Chemical Etching Advantages

• Low cost sampling
• Wide variety of metals can be etched
• No restriction for hardness of material
• No stress
• No burrs
• Quick, easy and cost effective tooling and design changes
• Short leadtimes (hours)
• Presise tolerances (up to ±10% of material thickness)
