(mnozil brass tuba muckl)Copper grade type

1、Copper grade:Color is purple pure copper material。Copper materials also include pure copper、Oxygen-free、Phosphate and special copper materials。

2、Brass:Copper zinc alloy material。

3、Bronze:Original copper tin alloy material,Later, the brass﹑Copper alloy material other than white copper。

4、White copper material:Adding elements as nickel、Silver white、Copper-based alloy material with metallic gloss。

China copper material grade representation method?my country National Standard(GB340-76)Regulation,Processing copper and copper alloy number named“Copper type code、Element content or sequence number after chemical symbol”Express,in,Copper type code to take the first upper capital letter of the first Chinese character Chinese pinyin,“T”Represents pure copper,“Q”Bronze,“B”White copper。

American copper material grade representation method

AmericaUNSNumber system(ASTME527)Regulation,Copper and copper alloy are used5Bit number as a code,Expressed as “C+xxxxx(Five digits)”,in,Processing copper“Cl0000?C15999”,Processing copper alloy is“C16000?C79999”。This code system is in the past3 Based on the number of digits,Developed by the American Materials and Test Association and the US Motor Engineers Association,And become the US metal and alloy unified number code system(UNS)Composition part。

Japanese copper material grade method

Japanese industrial standard(JIS)Processing copper alloy sign method and the United StatesUNSThe number is basically the same(More than one digit)。which is:C+XXXX(Four digits)。The first digit represents alloy series,use2~9Express。The meaning of each number is as follows:

2——Copper zinc;

3——Copper zinc lead line;

(mnozil brass tuba muckl)4——Copper zinc tin system alloy;

5——Copper tin、Copper tin lead alloy;

6——Copper aluminum、Copper silicon、Special copper zinc alloy;

7——Copper nickel、Copper nickel zinc;

German copper material gauge method

Industrial standard in Germany(din)middle,There are two systems for non-ferrous metal materials.。One is based on chemical elements、Mark letter and arabic number composition;Another kind7Bit number code system。In currentDINTechnical standard file,Two systems,Mutual control list。

AA method based on chemical elements

according toDIN1700—1954Provisions,The granding of copper and copper alloy is generally composed of two parts.:

(1)Description Mark letters of manufacturing methods and applications。E.g:See the pure copper in the table;

(2)Directly marked alloy ingredients。E.g:See the copper alloy in the table。

BNumber code

existDIN17007—1956Provisions,7The form of the digit code is as follows:

X·XXXX·XX(which is:Group·Category number·Additional number)

(mnozil brass tuba muckl)in:Group——Total10Large group,Copper and copper alloy are the first2Group;

Category number——Specific alloy,Mainly according to the chemical composition of the material、Preparation method;

Additional number——To mark such as smelting、pouring、The heat treatment method and whether it is hardening and profile、Surface condition, etc.。

The specific number code of German copper and copper alloy is shown in the table。
