3004 aluminum plate
Overview
3004 series aluminum alloy is also a series of aluminum-manganese alloy, high strength than 3003, excellent formability, good corrosion resistance, higher strength than the 3003 alloy parts.
Features
3004 for the AL-Mn alloy, is the most widely used of a rust-proof aluminum, the strength of this alloy is not high (slightly higher than the industrial aluminum), can not heat treatment strengthening, so the cold approach to improve its mechanical properties : In the annealed state has a high plasticity, hardening in the semi-cold when the plastic is still good, cold work hardening plasticity is low, good corrosion resistance, good weldability, poor machinability. Use mainly for applications requiring high plasticity and good weldability, low load parts in liquid or gaseous media such as mailboxes, gasoline or smooth oil conduits, various liquid containers and other small load parts made with deep drawing: Wire used for rivets
Usefulness
3004 aluminum formability, solubility, corrosion resistance are good. For processing needs Good formability, high corrosion resistance Good weldability of parts parts, or both the performance of these requirements and the need for more than 1XXX alloy strength of work, such as kitchen utensils, food and chemical products disposal and Storage tanks, tanks for liquid products, cans, various pressure vessels and piping for sheet metal processing, heat sinks, fuser plates, photocopiers drums, shipboards 3004 Aluminum strip for chemical products consumption and storage installation, Building materials, building baffle, cable ducts, sewers, all kinds of lighting components, beverage cans, Langban, building materials, color aluminum, electric lamps.

Aluminum alloy state and code description
1. Scope: This specification rules the deformation of aluminum alloy state code. This specification applies to aluminum and aluminum products. 2. Basic Criteria 2.1 The basic status code is represented by an uppercase letter. 2.2 subdivision status code with the root status code followed by one or more Arabic numerals. 2.3 The basic state code The basic state is divided into five kinds of code name Description and application of F-free processing state Suitable for the molding process, the hardening and heat treatment conditions on the product without special request, the state of the mechanical properties of products without rules. O annealed state for complete annealing to obtain the minimum intensity of processed products. H Work-hardened state For hardened, progressive strength products, the product can be subjected to additional heat treatment that reduces the strength after work hardening (or without). W SOLIDIFIED HEAT TREATMENT STATE OF DISPOSAL STATE An unstable state only applies to alloys that are naturally aged at room temperature after solution heat treatment. This status code only indicates that the product is in the natural aging phase. T heat treatment (different from F, O, H state) for heat treatment, with (or without) work hardening to reach a stable product. T code must be followed by one or more Arabic numerals. The first digit after the T indicates the type of heat treatment (from 1 to 10), and the digits below indicate changes in heat treatment details. Such as 6061-T62; 5083-H343. Exterior treatment of aluminum alloy sheet by the appearance of disposal can be divided into non-painted products and painted products two categories. 1) non-painted products (1) can be divided into hammer pattern aluminum (irregular pattern), embossed plate (with regular pattern) and pre-passivation of alumina surface treatment plate. (2) Such products do not paint in the appearance of the plate, the appearance of the appearance of the request is not high, the price is low. 2) paint products (1) Classification: according to the coating process can be divided into: spray-coated products and pre-roll coating; by paint varieties can be divided into: polyester, polyurethane, polyamide, modified silicon, epoxy Resin, fluorocarbon and the like. (2) a variety of coatings, the main performance difference is the ability to resist ultraviolet sunlight, which is the most commonly used in the front coating for the fluorocarbon paint (PVDF), its ability to resist UV strong; Or an epoxy coating as a maintenance paint. In addition the positive can also be attached to a layer of tearing the maintenance film.
