Beware of the Brass
September 2019

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

December 2018
If you haven’t used Europress yet, it’s probably because you’re not sure what it costs or if it has proven benefits, and you really don’t want to talk to a sales rep. You’re not alone. Engineers are often surprised to find that:
- You don’t have to get kitted out with expensive tooling to use Europress. Utilise our hire tooling fleet, fall in love with Europress, then invest in your own tooling down the track.
- 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.
- 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.
- 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.
- While materials may cost more, the installed cost, which is the true cost, is much lower due to the speed of installation.
