The new copper-manganese alloy is characterized by increased strength and improved casting properties. According to research director Professor Kevin Trumble, the goal of the work is to create lead-free materials to ensure a safe water supply.
Plumbing elements traditionally consist of bronze parts, which are difficult to process, as a result of which numerous defects appear during hardening, including shrinkage pores.
Researchers propose a Cu-Mn alloy with a special structure that prevents the formation of micropores during solidification. Products made from it harden in a narrow temperature range and are characterized by excellent strength, capable of replacing thin-walled parts.
A complex substance can be used in the manufacture of water pumps, valves, plumbing and marine. The economic feasibility of the opening lies in the low price of manganese, which saves on the production of important goods.
