Beware of the Brass

September 2019

Not all copper alloys are created equal - so it’s important to verify their composition when using them in raw water applications.

Brass is an alloy of copper and zinc. The proportions of each give brass different mechanical properties. In short, the reason for the copper is that it is unreactive, however it is very malleable and easily shaped and on the other hand, zinc is reactive but very strong and durable. By combining the two and creating brass, we have the “best of both worlds” with a product that is unreactive and strong – perfect for plumbing fittings and valves

  2. Press-fit is not a ‘fad’ and you’re not a ‘guinea pig’ if you try it. It has been used in Europe for over 25 years, and is trusted in NZ by Coca-Cola, Fonterra, Genesis Energy, Grey Base Hospital, and many more.
  3. If you’re a welder, Europress is not a threat to your skill. It is a complimentary string to your bow. It will not take over all your welding work. Most of our clients are welders.
  4. As we know from our power bills, hydro-power companies are in the process of producing liquid gold. One hour of downtime can cost them more than $100,000! Contact Energy choose Europress, because it’s speed of installation means less downtime, and its reliability and ease-of-adjustment means future downtime won’t be an issue.
