Overview

Aluminum bar is supplied as round, square, rectangular, or hexagonal stock for machined components, transport equipment, fixtures, electrical parts, and general engineering. Alloy and temper selection controls strength, machinability, weldability, corrosion behavior, and response to anodizing. Buyers should state section size, dimensional tolerance, straightness, surface, length, ultrasonic or alloy verification needs, and any saw-cut blanks. For a controlled quotation, state the alloy and temper, governing ASTM, EN, or GB standard, product form, thickness or section dimensions, tolerances, surface condition, processing, quantity, packing, and destination port. Alloy-temper combinations are reviewed against…

Packing & delivery

Order-specific packing

Aluminum is packed to limit moisture, staining, edge damage, and metal-to-metal abrasion. Depending on form, the export pack can use waterproof film, interleaving paper, edge boards, strapped skids, wooden cases, coil eye protection, or capped bundles. Unit weight, lifting method, container limits, protective-film requirement, destination climate, port, and discharge equipment are confirmed before loading.

Quality assurance

Documents as ordered

Inspection follows the accepted alloy, temper, dimensions, tolerances, surface condition, and applicable product standard. The agreed scope can include dimensional checks, visual surface review, mechanical-property documentation, alloy verification, coating or anodizing checks, and lot traceability. Certificate type and any third-party witness or laboratory requirement must be stated before production or stock allocation.
