Instructions
Pure aluminum
• A (B, C) is preceded by "E" for electrical use • Shape letter designation + sequence number + A (B, C) Sometimes added state letter code at the end • 4-digit group (number on the leading digit is 1) At the end of the grade, "A" is sometimes added to indicate that it is an alloy derived from the United States.
Purity decreases sequentially Example: E1B, E57S, F1B, G1A, S1A, R1B: Shape letter code: B—bolt screw; C—clad aluminum plate or strip; E—rod, profile; F—forging; Wire; P - sheet; R - rivet wire; S - sheet or strip; T - drawn tube; V - extruded tube, hollow profile. A, B, C—Grade Number Example: 1080, 1050A, 1350 1—industrial pure aluminum; the second digit indicates the number of controlled impurities; the third and fourth digits indicate the percentage of pure aluminum and aluminum after the decimal point Low content
Aluminum alloy
• H or N+ shape letter code + sequence number • 4 digit group (number of leading digits is 2-9) The addition of “A†at the end of the brand indicates that it is an American alloy derived system
Example: HB15, HE9, HR15, NE4, NF8, NG3H - Non-heat-treatable; N - Heat-treatable; see "Pure Al" for the letter designator Example: 3103, 5556A, 6061 Represents the classification code 2—Aluminum, copper, and magnesium; 3—Aluminum-manganese; 4—Alumino-silicon; 5—Al-manganese; 6—Silicon and magnesium; 7—Al-zinc-magnesium-copper;8— Aluminum and other elements
Cast aluminum alloy
LM+ sequence number (can be added at the end)
LM——Aluminum casting code
Pure copper
C+3 digit sequence number
Example: C101, C105, C—Pure Copper
Copper alloy
Copper alloy type letter code + 3-digit serial number
Examples: CA103, CB101, CN105 Types of copper alloys Alphanumeric code: CA—Aluminum bronze; CB—Beryllium bronze; CC—Chromium bronze; CN—Cu-Ni alloy;CS—Silicon bronze; CZ—Brass; NS - zinc white copper; PB - phosphor bronze
Copper and copper alloy solder
C+ sequence number
Example: C7,C11,C20,C—copper
Cast copper alloy
• Element type letter code + sequence number, for example: AB1, CN2, CMA1, LPB1 (end of individual tag plus status code, such as CC1-TF) • Other types of letter code + sequence number, for example: G1, HTB1, HCC1 Individual mark at the end Add state code, such as G3-TF
Element Category Letter Code: AB—Aluminum Bronze; CC—Copper-Chromium Alloy; CMA—Copper-Manganese-Aluminum Alloy; CN—Cu-Ni Alloy;CT—Copper Tin Alloy; LB—Lead Bronze; LPB—Lead Silicon Bronze; PB - Phosphor Bronze Other categories Alpha Code: DCC - Hard Die Casting Brass; HCC - High Conductivity Copper; HTB - High Strength Brass; G - Gunmetal; LG - Lead Cannon Copper; PCB - Die Casting Brass; SCB - Brass Casting; State Code TF stands for solution treatment plus precipitation
magnesium alloy
• MAG - product shape letter code + 3 digits category number • Mg - main added element symbol and nominal percentage + other added element symbols and nominal percentage
Example: MAG-F-101 and MAG-S-111 products have the same letter code as aluminum alloys: Mg-Al3Zn1M, Mg-Zn6Zr
Cast magnesium alloy
MAG+ sequence number
Example: MAG2, MAG5
Nickel alloy
NA+ sequence number
Example: NA1, NA11, NA—Ni-base alloy
Casting nickel alloy
ANC+ sequence number, some with A, B, C category numbers at the end
Example: ANC5C, ANC15, ANC18A
Titanium alloy
The grades of income are BS aerospace professional standards. The grades are directly represented by their standard numbers.
Example: BS2TA13, BSTA20 TA - Tantalum and Tantalum alloys; digits before TA indicate revised order; numbers after TA are sequential numbers
Pure tin
T+ sequence number
Example: T 1 ,T 2 ,T 3
