Mechanical properties of bronze

Are you interested in the mechanical properties of bronze from the supplier company AvecGlob? Here you will find the necessary information on this topic.

General information

Bronze — tin alloy of copper, is extremely durable and resistant to atmospheric corrosion. Bronze has been used since prehistoric times for the manufacture of processing tools, weapons, statues and ornaments. The alloy has a relatively low melting point, so it is easy to melt using charcoal and primitive blacksmiths. Sometimes other metals such as lead, gold or silver are added to the alloy to change the color, improve the finish or improve the fluidity of the bronze.

Alloy composition

The first bronze alloys usually consisted of copper, tin and small amounts of noble metals or lead. The amount of tin can reach 40 percent, but the classic bronze alloy and today’s commercially available bronze make up 10 percent of tin and 90 percent of copper. Manganese is added to the bronze used for ship propellers, because it resists the corrosion of salt water. Iron, nickel, silicon and aluminum are added for strength in fitters and tools, because bronze is intrinsically safe when impacted.

Strength

The strength of bronze depends on the composition of the alloy and ranges from 550… 600 MPa for standard bronze up to 800 MPa for aluminum bronze, and up to 900 MPa for manganese bronze.

Supplier — AvekGlob Company — offers to purchase assortment of various bronze alloys of domestic and foreign brands. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.

Hardness and fluidity

Accordingly, the yield strength is from 190 to 900 MPa, which makes it possible to effectively use bronze blanks in the processes of metal forming. The Brinell hardness ranges from 65 to 225 HB. Modern aluminum and manganese bronzes are used in marine fittings, bearings and pumps, where high strength and hardness are required.

Melting temperature

A typical ancient bronze had a melting point of about 1100 degrees Celsius, which was near the upper limit of the temperature range that can be reached in prehistoric furnaces.

Resistance to corrosion

Natural bronze is a non-ferrous metal, but on the statues and other sculptures in the moist air patination quickly develops, which protects the bronze from further damage. Patina can vary in color from greenish to dark brown. Bronze is unstable when there are vapors of chlorine or sulfur in the atmosphere.

Supplier — AvekGlob Company — offers various types of rolled and cast bronze from domestic and foreign production. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
