LARGE SELECTION OF

Bronze sheets and strips

We are a producer of metal alloys with copper, including bronze. We offer bronze sheets and bronze strips in a diverse selection – in terms of composition and in various sizes. The type of bronze depends on the proportion of the metal content, and above all the amount of the second metal or semi-metal, e.g. aluminum, beryllium, tin, silicon or manganese. Our alloys, from which bronze strip and bronze sheet are produced, are manufactured in accordance with Polish PN and European PN-EN standards. We offer, among others, tin bronze B6 (CuSn6) and B8 (CuSn8), silicon bronze BK31 (CuSa3MN1) or CuAl aluminum bronze.

In addition to various types of bronze, we also produce high-quality brass, copper, kupal and other sheets and strips.

HIGH QUALITY

Abrasion Resistant Bronze

Recipients of our bronze strips and bronze sheets use them to produce coins, springs or elements working in sea water. The engineering industry creates precision components that must be extremely abrasion-resistant, and the electromechanical industry – heat-resistant parts of devices. Due to its plastic advantages, bronze is often used in foundry, e.g. as a material for monuments.

We offer brown tapes with a thickness of 0.1 mm to 2 mm and a width of 5 to 360 mm. Our bronze sheets have the following dimensions: thickness from 0.2 mm to 30 mm, width 360 mm or 600 mm, length up to 2000 mm. The dimensions of the bronze sheets depend on the type of alloy. We invite you to contact our specialists and arrange all details in a direct conversation.

Bronze is an alloy of copper with tin or another metal which has a copper content of at least 80% by weight. The melting point fluctuates between 940-1084 degrees Celsius, while the density – 7.5–9.3 g / cm³.

Bronzes have many invaluable advantages, including durability (they are very resistant to weather conditions and corrosion). They are easy to work with and harden, and they also perfectly relieve friction.

Walcownia Metali Nieżelaznych “ŁABĘDY” deals with the creation of such elements as bronze sheet and bronze strip. The material used in the production process are the so-called bronzes for plastic working, from which, in addition to sheets and strips, bars, wires and pipes are also made.

However, the detailed application of bronzes for plastic working depends on their composition, on the basis of which the following are distinguished:

  • Aluminium bronze

    As the name suggests, mostly aluminum (4-11%). May also contain iron, manganese and nickel. The symbols for aluminum bronzes are BA5 (CuAl5), BA8 (CuAl8), BA93 (CuAl9Fe3), BA1032 (CuAl10Fe3Mn2), BA1044 (CuAl10Fe4Ni4), BA92 (CuAl9Mn4). They are usually used in the chemical, electromechanical and marine industries.

  • Beryllium bronze

    Similarly, with the highest content of beryllium (from 1.6% to 2.1%). May also contain nickel with cobalt and titanium. The symbols for beryllium bronzes are BB2 (CuBe2Ni (Co)), BB1T (CuBe1,7NiTi), BB2T (CuBe2NiTi). They are used in the chemical and electronics industries.

  • Tin bronze

    It will come as no surprise if it is said that it is mostly made of tin (1-9%). In addition, it can also contain zinc, lead and phosphorus. Tin bronze symbols are B2 (CuSn2), B4 (CuSn4), B6 ​​(CuSn6), B43 (CuSn4Zn3), B443 (CuSn4Zn4Pb3), B444 (CuSn4Zn4Pb4). They are part of the construction, electromechanical and mechanical industries.

  • Silicon bronze

    It holds 2.7% to 3.5% of silicon and 1.0% to 1.5% of manganese. Its symbol is BK31 (CuSi3Mn1). It is used in the chemical and electromechanical industries.

  • Manganese bronze

    It holds 11.5% to 13% manganese and 2.5% to 3.5% nickel. Its symbol is BM123 (CuMn12Ni3). It is used in the electrical industry.
