Lead ingots are rectangular, with protruding ears at both ends, blue and white metal, soft.Density 11.34g/cm3, melting point 327
Use
Lead ingots is mainly used in manufacturing battery, coating, warhead, welding material, chemical lead salt, cable sheath, bearing material, caulking material, pap alloy and X-ray protective material.
batteries Lead ingots are widely used in� the manufacture of batteries, cables and fuse, as well as alloys and chemical pigments.Lead ingots shall be shipped by means of transport without corrosive substances to prevent them from being rained on.Lead ingots should be stored in a ventilated, dry, non-corrosive material storage room.The white, off-white or yellow-white films formed on the surface of lead ingots during the transportation and storage are determined by the natural oxidation properties of lead, and shall not be used as the basis for scrapping.
Regenerated lead is increasingly attach importance to environmental protection in recent years, strengthening non-ferrous metal resources recycling situation of emerging industries, the raw materials more than 85% from the waste battery recycling, promote recycling of resources, alleviate the pressure of the lead resource requirements, and reduce the pollution of lead, but most enterprises backward technology, high energy consumption, low lead recovery.
The formulation of the national standard of Lead Ingot supplier plays an important role in standardizing the management of recycled lead industry, perfecting the rules of market operation and promoting the development level of the industry.The formulation of national standards for lead ingots will expand the popularity and reputation of a considerable number of industrial areas in the industry, which is of great significance to promoting the development of the recycled lead industry.
Introduction
Nickel is a silver-white metal, in the air is easy to be oxidized by the air, the surface of the formation of some hair of the oxide film, so people often see the color of nickel hair.Nickel is hard, ductile, magnetic and corrosion resistant, and highly polished.Nickel is also abundant in the earth's crust.Nickel silicate ore or sulfur, arsenic, nickel compounds exist in nature.
The development of nickel
In recent years, the production and consumption of nickel in the world is relatively stable, the supply and demand of nickel in the world market mainly changes with the development of the stainless steel industry. With the increase of the application of nickel in the consumption of stainless steel industry, the smelting technology of ferronickel has made great progress, and the output of high-grade ferronickel has been greatly improved.Russia, Canada, new caledonia, Indonesia, Australia and Cuba account for about 80% of the world's nickel production and exports.
1. Ferro Manganese is an alloy of Iron and manganese, with manganese between 65.0%~90.0%, as deoxidizer and alloying element additive. Divided into furnace ferromanganese and blast furnace ferromanganese.
2. Main categories: high carbon ferromanganese (carbon 7%), medium carbon ferromanganese
(carbon 1.0~1.5%), low carbon ferromanganese (0.5% carbon), metal manganese, Spiegel, Silicon-manganese alloy.
3. International general standard for carbon ferromanganese containing mananese with 75 ~ 80%. To adapt to the conditions of low grade raw ore, China provides manganese lower grades (furnace ferromanganese manganese containing more than 65%, blast furnace ferromanganese manganese containing more than 50%).

Characteristics
Ferrochrome is a kind of ferroalloy with chromium and iron as main component and it is one of the main alloy agent in iron and steel industry. Ferro chrome contains chromium between 50% and 70%.
Chrome is mainly used to improve the antioxidation and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhension oxide film. Then it stops being oxidized or decelerates being oxidized. Micro-carbon ferro chrome is applied to making stainless steel, acid-resistant steel and heat resistant steel.
The Specifications of Ferro Chrome
HCFeCr Cr: 65% min, C: 8.5% max.
Manganese Metal Lump is an additive for steel making and Non-steel Alloys. It can go deep inside of liquid Steel to achieve the final manganese concentration required in steel.
Electrolytic Manganese Metal Flakes has been widely used in production of steel and stainless steel and Non-Steel alloys. It plays important role in desulfurization deoxidation and alloying. Manganese can increase strength tenacity, abrasive resistance, and corrosion resistance of steel.
Electrolytic manganese is the elemental metal precipitated by acid leaching of manganese oreã??
Applications:
With high purity,low impurities,Electrolytic Manganese Metal Flakes are widely used in Iron and steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, electrode industry, aerospace industry and other fields.
Electrolytical manganese mainly used as an additive,to increase the strength, toughness, abrasion resistance and corrosion resistance of alloys in the field of steel smelting, manganese copper alloy,manganese aluminum alloy,200 series stainless steel.
Ferro chrome (FeCr) is an ferro alloy of chromium and iron, containing 50% to 70% chromium. The ferro chrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. It can divide into Charge FeCr, Carbon FeCr, Low carbon FeCr and Micro carbon FeCr
Vanadium nitrogen alloy is a new alloy additive which can replace ferro vanadium for the production of microalloyed steel.
NiV can improve the mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance,and make the steel have good weldability.
At the same strength,use NIV can save vanadium addition20-40%,thereby reducing the cost.
NiV alloy can be used in structural steel, tool steel, pipeline steel, reinforcing bar and cast iron.
Vanadium-nitrogen alloys can be effectively microalloyed simultaneously in high strength low alloy steels to promote the precipitation of carbon, vanadium and nitrogen compounds in steels,more effectively enhance sedimentation and grain refinement
