EN 755-1 Aluminum and Aluminum Alloys - Extruded Bar, Rod Pipe and Profiles - Part 1: Technical Conditions for Inspection and Delivery

The standard EN 755-1, a European standard, describes the technical conditions for the inspection and delivery of forged aluminum and aluminum alloy extruded bar, bar tube and profile for general engineering applications. However, this standard does not apply to:

Forged stock (EN 603 series of standards),
Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 (EN 12020 series of standards)
Products delivered in rolls (EN 13957 standard)
Coiled tubing cut to length (EN 13957 standard)

For the purposes of this standard, an order document refers to a document or set of documents agreed upon between the supplier and the buyer at the time of ordering. Essentially, the order document should include:

Shape and type of product (can be extruded bar, rod, tube or profile, EN 573-3 standard applies for chemical composition limits, EN 515 standard applies for tempering definition)
EN 755-2 standard is valid for mechanical property limits.
Tolerances for inside and outside diameter should indicate whether the suggested tolerances are average or include ovality.
Tolerances on dimensions and form according to the appropriate European standard or a drawing.
Quantity (mass, number of parts, total length and quantity tolerance).
Any requirement for inspection documents.
Special requirements agreed between supplier and buyer.
For products intended to be anodized by the buyer, the order document must also contain information on the specific surface treatment intended, with reference to the relevant European standard.

An aluminum alloy is an alloy in which aluminum is the predominant metal. Typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. It is divided into two basic groups as casting alloys and wrought alloys. Both of these are divided into heat-treatable and non-heat-treatable subgroups. About 85 percent of aluminum is used for forged products such as rolled sheet, foils and extrusions.

Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, tests for aluminum and aluminum alloys, extruded bars, bar pipes and profiles within the scope of EN 755-1 standard. also provides services.
