Giltech is a non-ferrous foundry, that has been in business since 1881, that specialises in the casting of bronze alloys, copper and aluminium castings. 

The most common bronze alloys cast are Low Lead Leaded Gunmetal (LLG2), Aluminium Bronze (AB2), Nickel Bronze (NiB) and Manganese Bronze (MnB).  We also cast a number of specialised alloys. 
The aluminium alloy we cast is CC601 (LM25) which is able to be heat treated. While we don't do heat treating we can arrange to have this done.

Giltech casts over 20 tonnes of metal a month into castings weighing up to 250kgs using only certified ingot. 
The demand for Aluminium Bronze (AB2) has grown to such an extent that one of our furnace crucibles is now only used for this metal. 

Castings supplied for pressure applications can be tested air under water at 620 Kpa. 
We specialize in the machining of large runs of products utilising our Rotary transfer machines.  In addition to this should you want any of your castings machined our machine shop is equipt with CNC Mills, lathes etc 

We can provide Certificates of Analysis and/or Conformity which can include melt codes cast on each product. Tensile and non destructive testing can also be arranged if required.

Giltech has been ISO 9001:2008 certified since 1992 and this certification has enabled us to develop an increasing export market with over 60% of our production being exported to Australia.

We have very good technical assistance available to help you with your product development. Contact us for a quote...
