Basic knowledge on five kinds of metals is as follows:

I. Definition

   The so called fiive kinds of metals are referred to as gold, silver, copper, iron and tin.

   Gold

   Silver

   Copper

   Iron

   Tin
 

II. Awareness of metal raw materials regularly used.


1.Brass
Brass is an alloy made of copper and zinc with its color turned from yellow red to light yellow when its zinc content increased. If there are only copper and zinc contents in it, it is called brass. The machinability of brass is much better than that of pure copper. Generally speaking, it is not easy to get rusted or corroded. In addition, it has good ductile property so that it can bear for hot-press and cold-press processing as well.

2.Bronze
  Bronze is an alloy consisting primarily of copper and tin, but traditionally other copper alloys are all called bronze except brass and white copper in industry.

3.Phosphor Bronze
  Phosphor bronze is an alloy of copper with a significant phosphorus content.

4.Beryllium Bronze
 
Beryllium bronze is an alloy of copper with beryllium content.

5.Copper
Copper is also called pure copper which is also called reddish-brown copper. It is an excellent conductor of electricity and heat which is ductile and malleable, easy for hot-press and cold-press processing as well. It is widely used for making the products with good conductivity.

6.Stainless Steel
Stainless steel is referred to stainless and acid resistant steel. It is a type of steel highly resistant to corrosion and rust under atmospheric, steam, fresh water conditions of the weak corrosion media which is called stainless steel; while it is a type of steel highly resistant to chemical media corrosion (such as acid, alkali, salt and etc.)which is called acid resistant steel. As there are different chemical compositions, there are different corrosion resistance for these two types of steel. Ordinary stainless steel is not resistant to chemical media corrosion while acid resistant steel is generally resistant to rust.   

7.SPTE
SPTE is an alloy made of tin(Sn)and iron(Fe), of which Sn is used as a galvanized layer. It is also called tin galvanized iron. ( Please note the difference of white iron(Zn,Fe), of which Zn is used as a galvanized layer. It is commonly known as zinc galvanized iron.) SPTE is commonly called for tinplate which is referred to cold-rolled, low- carbon steel sheet or steel strip with commercial pure tin galvanized on both sides.

Tin mainly plays the role for being resistant to corrosion and rust. It has a good combination of strength and mouldability from steel and corrosion resistance, welding and beauty from tin.

8.Aluminum  Alloy
Aluminum alloy is a general name called for those alloys in which aluminum is the predominant metal. The typical primary alloying elements are copper, silicon, magnesium, zinc and manganese. The typical secondary alloying elements are nickel, iron, titanium, chromium and etc. Aluminum alloy has low density but comparatively high strength similar to or exceeding that of quality steel with good ductility which can be processed into wrought products. It is a good conductor of electricity and heat with corrosion resistance which is widely used in industry with quantity consumed only after steel.
