Manganese bronze is among the top robust alloys, which basically comprises of copper, manganese, and a small amount of other elements mainly zinc, aluminum, and iron. The chemical composition of each grade differs, but copper is its most abundant component. The amount of copper in the tank can range between 55% and 60%, and the amount of zinc and manganese can be between 20% and 25% and 3% and 5% respectively, while some other elements may be found in trace amounts. The manganese bronze alloys are grouped into grades depending on the BASIC chemical properties such as tensile strength, hardness and corrosion resistance. These grades determine the most effective strength alloy for purposes like marine-grade hardware, bushings, valves, and actuators. Tables, charts and documents with properties, composition and fields of use of the manganese bronze grades are the basic references for designers, metallurgists and manufacturers, those involved with the production and utilization of this diverse alloy.
Manganese-bronze alloy is an all-rounder with a combination of strength, wear-resistance and easy workability that it is used in marine applications and machinery such as cranes and press machinery. It is chemically composed of conservatively about 55-60% copper, 39-40% zinc, and 0.5-2.0% manganese. This macro-nutrient has compound structures such as water, fats and carbohydrates, respectively. The amounts of trace elements like iron, aluminum, and lead would be present as well in much smaller quantities. This addition incorporates into the steel alloy the outstanding quality of immense sturdiness and a strong ability to deal with a variety of damage, making it a perfect fit for parts that are constantly exposed to extreme environments. Manganese bronze is the favorite choice among many industries in places environmental conditions are harsh as it is reliable and durable under pressure.
