3004 aluminum plate

3004 aluminum is a general purpose alloy with excellent corrosion resistance. Its composition is similar to 3003 aluminum sheet, however, a slight addition of magnesium increases its strength. One disadvantage of this grade is that it cannot be heat treat

Product introduction

The 3004 series aluminum plate also belongs to a series of aluminum-manganese alloy, with higher strength than 3003, better formability and corrosion resistance, which requires parts with higher strength than 3003 alloy

3004 aluminum plate is also a kind of al-mn alloy, with higher strength than 3003 aluminum plate, higher strength than 3003 aluminum plate, good formability, solubility and corrosion resistance, so parts with higher strength than 3003 alloy are required.We focus on the production of hot rolled 3004 aluminum plate, excellent product performance, with the original factory warranty, welcome to inquire and order.


Typical Alloy

3004 Aluminum plate

Material Temper

H26,H28,H112 etc.







Typical Products

Lamp head material, shutter material, wide screen wall panel, LCD back plate material, color coating with aluminum base material .

Material properties

3004 for AL - Mn alloy, is one of the most widely used antirust aluminum, this kind of the strength of the alloy is not high, slightly higher than that of industrial pure aluminum), can't heat treatment to strengthen, the cold working method is adopted to improve its mechanical properties: in annealing state has high plasticity, in a cold work hardening plasticity is good, when the cold work hardening plasticity is low, good corrosion resistance, good weldability, cutting performance is bad.Applications are mainly used for low load parts which require high plasticity and good weldability and work in liquid or gas medium, such as mailboxes, gasoline or lubricating oil pipes, various liquid containers and other small load parts made of deep pull: wire for rivet.


Aluminum sheet 3004 has good formability, solubility and corrosion resistance.Used for processing need good formability, high solderability good resistance to corrosion of parts, components, or both require these performance and needs to have more than 1 XXX alloy high strength work, such as kitchen utensils and appliances, food and chemical products processing and storage device, transport liquid product tank, tank, with sheet processing all kinds of pressure vessel and pipeline generally implements, radiator, makeup, copy machine roller, ship material.

3004 aluminum strip is mainly used in the production and storage of chemical products, sheet processing, building materials, building baffles, cable pipes, sewers, various lamp parts, beverage cans, wave boards, building materials, color aluminum plates, lamp heads.

Chemical composition

Aluminum Al: margin;
Silicon Si: 0.30;
Copper Cu: 0.25;
Magnesium Mg: 0.8 ~ 1.3;
Zinc Zn: 0.25;
Mn: 1.0 ~ 1.5;
Fe: 0.7;
Other: 0.05.

Mechanical properties

Tensile strength b (MPa) : 150 ~ 285 ° c
Elongation = 10 (%) : 1 ~ 16
Annealing temperature: 415℃.

Relevant technical standards
National standard for aluminum strip (GB/T 3880-2006), applicable to the unified standard for aluminum strip material.

Surface treatment

Aluminum alloy plate can be divided into two categories: non-painted products and painted products according to the surface treatment.

1) non-painted products
(1) it can be divided into hammer aluminum plate (without regular pattern), embossed plate (with regular pattern) and pre-passivated alumina surface treatment plate.
(2) such products do not paint the surface of the plate, the appearance of the surface requirements are not high, the price is low.

2) paint products
(1) classification:
According to the coating process can be divided into: spray plate products and pre-roll coating plate;
According to the types of paint can be divided into: polyester, polyurethane, polyamide, modified silicon, epoxy resin, fluorocarbon.
(2) in a variety of coatings, the main performance difference is the resistance to ultraviolet rays of the sun. The most commonly used coating on the front is fluorocarbon paint (PVDF), which has strong resistance to ultraviolet rays.The back surface can be coated with polyester or epoxy resin as protective paint.In addition, the front can also be attached to a layer of tear off the protective film.


Al 3004 of the packaging meets the export standard. Plastic film and brown paper can be covered for customers’ needs. A wooden case or wooden pallet is adopted to protect products from damage during delivery.
