To manufacture a consistent diecast component requires total confidence in the quality and consistency of the alloy used. The track record, systems and traceability at Brock Metal are second to none and ensure the highest level of confidence in our products at the design, specification and production stages.

All of our Zinc alloys conform to BS EN 1774 1998 and are manufactured from primary or virgin Zinc conforming to SHG (Super High Grade) or Zn1 grades which are 99.995% pure and themselves conform to international specifications such as EN1179.

As world class suppliers of a wide range of Zinc alloys the team at Brock Metal can help customers with a more detailed understanding of the relative performance and properties of different alloys to help improve the quality and castability of the final component, saving time and money throughout the production process.

Generic Terms for Zinc Alloys

Unlike other metals, a number of generic terms for zinc alloys have developed which still leads to considerable confusion to product designers and specifiers. And with secondary alloys still available on the market it is important that these generic terms do not allow their use where primary alloys are required. So we strongly encourage the identification of alloys through the relevant EN or International standard classifications. With our expertise, the team at Brock Metal can help you though this issue and ensure that you order the right alloy for the right project every time.

As well as the more generally available zinc alloys, Brock Metal also produces a number of special diecasting alloys including Ilzro 16, Zami, Spincast and US MIL spec 18001, a cathodic protection alloy.

Brock Metal can also make alloys to special chemistries to meet specific customer requirements though there may be volume requirements on these orders.
