Zinc is a metallic chemical element. It is naturally found everywhere in the environment. Chemically, it is represented by the symbol Zn. Zinc derived its name, supposedly, from the German word Zinke, which means 'tooth-lik' or 'pointed'. Zinc must have got such a name owing to its crystal form which is needle-like in structure..

Zinc derived its name, supposedly, from the German word Zinke, which means 'tooth-lik' or 'pointed'. Zinc must have got such a name owing to its crystal form which is needle-like in structure.. Features:  Zinc is bluish shiny silver metal, hardness 2.5, pure zinc malleable, containing a small amount of impurities are brittle. Good heat transfer, electrical conductivity, chemical properties of more reactive. Room temperature in the air more stable. Humid air generated in the layer of gray basic zinc carbonate can be used as protective film. Zinc has blue-green flame when burned. Reaction with water vapor at high temperature release of hydrogen. When heated with halogen, sulfur and other reactions. Easily with acid reaction, but the slow response of high purity zinc, if a small amount of copper sulfate solution, or with copper, nickel, platinum and other metal contact, the reaction accelerated. Soluble in alkali solution to produce zinc salts.

Lead alloys are used in a range of applications including: Solder: lead solder is used extensively by the electronics industry Terne plate:iron and steel can be protected against corrosion by coating the surface with a lead based alloy. Brass and Bronze Products:lead had traditionally been used in bearings and bushings to reduce wear and friction in certain type of machinery.

Nickel is known to have been discovered in 1751. As recently as a hundred years ago, it was still considered to be a worthless variety of copper. Miners in south-eastern Germany mistook a mixture of nickel and arsenic for copper. The name of the metal comes from the German word "Nickel" which was the name given to an evil spirit who was reputed to interfere with the work of miners.

The name of the metal comes from the German word "Nickel" which was the name given to an evil spirit who was reputed to interfere with the work of miners.   Features:  Nickel is a hard, silvery-white metal, which is malleable and ductile.  The metal can take on a high polish and it resists tarnishing in air.  Nickel is ferromagnetic and is a fair conductor of heat and electricity. Most nickel compounds are blue or green. It can have manybut its favored oxidation state is +2 like all transition metals it has high density,   has very high melting point (like most TM)   and can be used as a catalyst (as in the case of most TM)

Lead was probably one of the first metals to be produced by man, being known since 3500 B.C., in agreement with archaeological discoveries done in Egypt. The oldest lead piece is in the British Museum and dates from 3800 A.D.. The manner in which prehistoric people extracted lead from its minerals is not well-known. However, there are vestiges of very rudimentary furnaces, done of stone, where these people heated up the lead minerals with bonfires (that burned wood and coal) to extract the element      Features & Applications: Although uses for lead have decreased over the years, it still plays an important part of everyday life particularly as the starter mechanism for automobiles. The lead-acid battery, which performs this function, dominates the usage of lead, consuming over 80% of world production. The remaining 20% of production is divided into numerous end-uses including: underwater cable sheathing, ammunition, glassware, solder and roof sheeting.   Lead alloys are used in a range of applications including:   Solder: lead solder is used extensively by the electronics industry   Terne plate:iron and steel can be protected against corrosion by coating the surface with a lead based alloy. Brass and Bronze Products: lead had traditionally been used in bearings and bushings to reduce wear and friction in certain type of machinery.

Copper was the first metal mined and crafted by man, and has been the most important one in the oldest times of history, because it was available in great quantities and was initially extractable almost at the surface of ground. In addition, it was suitable to craft weapons and tools, art objects and ornaments.     Specifications:     Polyester        Code PEW has Thermal Capacity of 155°C           Diameter range from 4.06 mm to 0.091 mm (8 Swg to 43 Swg     Polyester-imide Code AIW Thermal Capacity is 220°C Diameter range from 4.06 mm to 0.091 mm (8 Swg to 43 Swg) Polyester Over Coated with Polyamide Coded as PEW-NY and PEWH-NY Thermal Capacity of 155°C and 180°C Diameter range from 4.06 mm to 0.091 mm (8 Swg to 43 Swg)                                       Polyester-imide Over Coated with Polyamide-imide         Code EIW-AI has         Thermal Capacity of 200°C         Diameter range from 4.06 mm to 0.091 mm (8 Swg to 43 Swg)            Polyurethane         Code UEW and UEWF                  Thermal Capacity of 120°C, 130°C and 155°C         Diameter range from 4.06 mm to 0.091 mm (8 Swg to 43 Swg)           Polyurethane Over Coated with Polyamide        Code UEW-NY and UEWF-NY                Thermal Capacity of 130°C and 155°C        Diameter range from 4.06 mm to 0.091 mm (8 Swg to 43 Swg) Features:  1.

Aluminum is the third most abundant element of the Earth’s crust, behind that of oxygen and silicon. Of the metallic elements, it is the most abundant, 7.3% by mass of the total crust. Due to Aluminum’s high affinity to bind with oxygen, it is not found in naturally occurring in its elemental state, but only in combined forms such as oxides or silicates.
