This product is a modern imitation of chinese bronze

The formation of Shandong glue County SanLiHe Longshan culture have unearthed two Bronze cone. Obviously, these bronze objects is not that the hands of people in prehistoric bronze smelting technology, but the use of copper-zinc Ore inadvertently get the zinc content of the Shang and Zhou dynasties, bronze is very low, generally in the 10-z-order of magnitude. Jue, a piece of bronze, is like a cup to warm or drink wine produced in the reign of the Emperor Mu.  Western Han Dynasty, the new board individual copper and zinc Gan money the shikimic the money, which some coins in zinc content of 7%, but this does not explain the occasion of the bronze money but produced in the Western Han Dynasty Xinmang because these copper-zinc alloy is an isolated phenomenon its zinc content was generally compared with a bronze in the true sense of the zinc content of 15% to 40% is much smaller, so we believe that the zinc coins of the Han dynasty in the mountain mint coins use copper-zinc Ore .
 According to the investigation of the mine and found Changwei, Yantai, Linyi and Hubei, Shandong has a resource-rich copper-zinc Ore, which make the smelting of copper containing a small portion of zinc to the Tang Dynasty Birds line, due to the standardization of money but material, so that the content of zinc in the coins are constant. This bronze has a wide spout, long tail, deep belly and round base setting on three knife-like feet. The difference between bronze and bronze? Phosphor bronze: copper alloy containing 2% to 8% tin, 0.1% and 0.4% phosphorus, I copper. Mainly used as wear parts and elastic components. Bronze: Bronze is an alloy composed of copper and zinc. If only composed of copper, zinc, bronze is called the ordinary bronze. By more than two kinds of elements composed of a variety of alloy known as special bronze. Such as lead, tin, manganese, nickel, lead, iron, silicon, copper alloy.
Bronze have a strong wear resistance. Bronze, copper, bronze, copper-nickel alloy, What's the difference? Copper constitute the alloy to pure copper matrix by adding one or several other elements. Pure copper was purple, also known as purple copper. Besides, the bronze is covered with the pattern of phoenix with drooping crest. Pure copper density 8.96, melting point 1083 ℃, with excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. Mainly used for the production of generators, bus, cable, switch gear, transformers and other electrical equipment and heat exchangers, pipes, solar heating devices, flat-plate collector such as thermal conductivity equipment. Copper alloys are divided into three categories of bronze, bronze, copper-nickel alloy. Bronze and zinc add an element of the copper alloy, with a beautiful yellow, collectively referred to as bronze.
Cu, Zn binary alloy that ordinary bronze or simple bronze. Three yuan more than the bronze that special bronze or complex bronze. Less than 36% of zinc bronze alloy by solid solution, with good cold working properties, such as zinc 30% of the bronze is commonly used to make casings, commonly known as the casings of bronze or 73 bronze. Bronze alloy of zinc between 36 to 42% by solid solution, of which the most commonly used is zinc 40% of the Tiananmen bronze. In order to improve the performance of ordinary bronze, often add other elements such as aluminum, nickel, manganese, tin, silicon, lead. Aluminum can improve the strength, hardness and corrosion resistance of the bronze, but the plasticity decreases, suitable for ocean-going vessel condenser and other corrosion-resistant parts. This product is a modern imitation of chinese bronze.
