World Lead Chemical Etching
Photofab take great care in the selection of the right metal for the component application. Wherever possible, Photofab use a special photo-etching grade, which is more uniform in thickness and flatter than normal stock. Our engineers and metallurgists will be pleased to advise on the grade of metal suitable for your application.
An extensive range of metals in various degrees of hardness and thickness are held in stock ready to meet a Rapid Delivery service. Metal thickness of 0.012 to 1.5 mm is suitable for through etching, while any thickness of sheet material can be surface etched.
The following list of metals is suitable for chemical etching, and many are held in stock. If you don’t see what you need please telephone us on 01480 226699 or contact us using the form below.

Our etching tabbing guidelines In order to further increase the precision of components and the ‘flawless look’ of decorative parts, Photofab ‘tab’ parts into sheets of metal. Tabs are slivers of metal, that serve to retain parts in sheet form. In other words, once completely etched, the components are not ‘loose’ parts, but instead are held into sheet form using …Read More
