Bushings play a crucial role in reducing friction and wear in various machinery and equipment, contributing significantly to their smooth and efficient operation. One of the preferred materials for crafting high-performance bushings is manganese bronze, specifically the C86200 and C86300 alloys. Let’s delve into their features, benefits, and why they make a great choice for bushings.
Understanding C86200 and C86300 Manganese Bronze
C86200 and C86300, both part of the high-strength manganese bronze family, are copper-based alloys known for their superior strength, durability, and resistance to wear. Their excellent mechanical properties result from the high content of manganese and aluminum, combined with iron, zinc, and a small percentage of lead.
C86200 Manganese Bronze – Also known as “High-Strength Yellow Bronze,” this alloy is composed of approximately 64% copper, 24% zinc, 5% manganese, 3% aluminum, 1% iron, and a small amount of lead. It is known for its superior load-bearing properties and wear resistance.
C86300 Manganese Bronze – Also known as “High-Strength Manganese Bronze,” this alloy consists of approximately 63% copper, 25% zinc, 6% aluminum, 3% manganese, and 3% iron. It has even higher strength and hardness than C86200, making it ideal for applications involving heavy loads and rough operating conditions.
