Oxidation Gold Aluminum 7075 Brake Part Bracket Car For Front Caliper

7075 material introduction
Elemental properties of combinations are expressed in maximum percentages unless a range or minimum value is listed.
(2) In order to determine appropriate numerical limits, the observed or calculated values ​​obtained from the analysis are in accordance with the standard rules (ANSI Z25.1)
to indicate a clear range.
(3) Except for non-alloys, the specified amounts of elements in alloys are usually indicated in the analysis report. But if during analysis
If other elements are suspected to exist or some elements are suspected to be in excess, further analysis should be carried out until confirmed.
(4) Either the content of aluminum in the unalloyed aluminum through the refining process is the difference between the total amount of other metals and 100% pure aluminum - the difference
at 0.01 percent or a little more. (2nd decimal place in percent)
(5) May contain up to 0.25% zirconium and titanium.
Zinc is the main alloying element in 7075. Adding magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, so that the heat treatment effect of the alloy is far better than that of the aluminum-zinc binary alloy. Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its resistance to stress corrosion and exfoliation corrosion will decrease accordingly. After heat treatment, very high strength properties can be achieved.
7075 materials are generally added with a small amount of copper, chromium and other alloys. Among the series, the 7075-T651 aluminum alloy is particularly high-quality, known as the best product in aluminum alloys, with high strength and far better than any mild steel. This alloy also has good mechanical properties and anodic reaction. Representative uses include aerospace, mold processing, mechanical equipment, tooling and fixtures, especially for the manufacture of aircraft structures and other high-stress structures that require high strength and strong corrosion resistance.
The basic principle
The base state code is represented by an English capital letter. 2.2 The subdivision state code is represented by the basic state code followed by one or more Arabic numerals. 2.3 Basic state code The basic state is divided into 5 kinds. Code Name Description and application F Free machining state is suitable for products that do not have special requirements for work hardening and heat treatment conditions during the forming process, and the mechanical properties of the products in this state are not specified. The O annealed condition is suitable for processed products that have been fully annealed to obtain the lowest strength. H Work hardening state Applicable to products whose strength is increased by work hardening. After work hardening, the product may or may not undergo additional heat treatment to reduce the strength. W Solution heat treatment state Treatment state An unstable state, which is only applicable to alloys that are naturally aged at room temperature after solution heat treatment. The state code only indicates that the product is in the natural aging stage. T heat treatment state (different from F, O, H state) is suitable for products that are stable after heat treatment (or without) work hardening. The T code must be followed by one or more Arabic numerals. The first digit after the T word indicates the basic type of heat treatment (from 1 to 10), and the subsequent digits indicate changes in the details of the heat treatment. Such as 6061-T 62; 5083-H 343 and so on. T1—cooled from molding temperature and naturally aged to roughly steady state. T2—annealed condition (for castings only). T3—natural aging after solution treatment and cold work. T31—natural aging after solution treatment cold work (1%). T36—natural aging after solution treatment cold work (6%). T37—natural aging after solution treatment cold work (7%), used for 2219 alloy. T4—natural aging after solution treatment. T41—quenching with boiling water after solution treatment. T411—air-cooled to room temperature after solution treatment, the hardness is between O and T6, and the residual stress is low. T42—natural aging after solution treatment. Processed by the user, suitable for 2024 alloy, slightly lower strength than T4. T5—Artificial aging after cooling from molding temperature. T6—Artificial aging after solution treatment. T61-T41+ artificial aging. T611—Solid solution treatment, boiling water quenching. T62—Artificial aging after solution treatment. T7—stabilized after solution treatment. Improve dimensional stability, reduce residual stress, and improve corrosion resistance. T72—overaging after solution treatment. T73—Grading aging after solution treatment, the strength is lower than T6, and the corrosion resistance is significantly improved. T76—Classification aging after solution treatment. T8—Artificial aging after solution treatment and cold work. T81—cold work after solution treatment, artificial aging. In order to improve the deformation and strength after solution treatment. T86—cold work after solution treatment (6%), artificial aging. T87-T37+ artificial aging. T9—Cold working after artificial aging after solution treatment. T10—Cool from the molding temperature, and then cold work after artificial aging. Tx51—stretching treatment to eliminate residual stress after solution treatment. The permanent deformation of the plate is 0.5~3%, and the permanent deformation of the bar and profile is 1~3%. X represents 3, 4, 6 or 8, such as T351, T451, T651, T851, suitable for plates, drawn rods, and wires, and aging without any correction after stretching and stress relief. T3510, T4510, T8510 are suitable for extruded profiles. After stretching and stress-relieving, they are corrected to make the straightness meet the tolerance and aging. Tx52—compression deformation to eliminate residual stress after solution treatment, 2.5% plastic deformation and aging after solution treatment, such as T352, T652. Tx53—Relieves thermal stress. Tx54—compression deformation in order to eliminate the residual stress after solution treatment of precision forgings.
