Special Aluminum Alloy 2/7 Series Aluminum

Special Aluminum Alloy Hub

2xxx and 7xxx special aluminum alloy routes for demanding projects.

When your drawing requires high strength, machining stability, forged stock, seamless tube, bar, profile or plate supply, Conglin helps you choose the right 2 series or 7 series aluminum route before quotation.

2xxx and 7xxx special aluminum alloy profiles bars tubes and machined materials
2xxx2024 plate, bar, tube and machined-part material review.
7xxx7075 plate, blocks, precision machining and high-load structures.
ProfilesSpecial extrusions, bars, seamless tubes and custom sections.
ForgingsForged discs, rings, plates, tubes and heavy-duty blanks.

Drawing-first quotation

Send the geometry, alloy target and application load before you lock the route.

2xxx and 7xxx aluminum can involve plate cutting, extrusion, reverse extrusion, forging, heat treatment and CNC machining. Conglin reviews your drawing so your team can quote the right production path, not only a material name.

For plate and block stockShare thickness, width, length, temper, flatness, ultrasonic or inspection requirement, and machining allowance.
For profiles, bars and seamless tubesShare section drawing, outside circle, wall thickness, straightness, temper and quantity range.
For forged partsShare blank size, projected area, final machined shape, heat treatment and inspection document needs.
For high-risk applicationsTell us the working environment, load direction, traceability requirement and approval documents your team needs.

Technical range for RFQ review

Use these capability ranges to prepare your 2/7 series inquiry.

Final feasibility depends on your drawing, alloy, temper and inspection standard. The ranges below help your team send the right starting information.

Tube referenceOD Φ6–Φ300 mm, ID Φ4–Φ240 mm, wall thickness from about 1 mm depending on alloy and temper.
Bar referenceRound Φ14–Φ300 mm, square 14×14–200×200 mm, hex inscribed circle Φ14–Φ260 mm, outside circle 30–300 mm.
Profile referenceCustom cross-sections, high-strength wall thickness review, outside circle 30–300 mm and drawing-based tolerance planning.
Forging referenceDie forging and free forging routes for projected area, thickness, length and width requirements that need machining allowance.
Inspection referenceMaterial certificate, dimensional report, surface check, machining inspection, packing photos and supplier-approval proof can be planned with your order.

Certification & Quality Systems

Use Conglin quality proof for supplier approval.

Material selection becomes easier when your engineering and sourcing teams can review lab proof, certificates and project qualification evidence together.

Certification

Quality proof before your order

Conglin supports international procurement teams with quality-system certificates, welding qualifications, inspection records and export-ready documents. The goal is simple: help your engineering, purchasing and compliance teams reduce supplier risk before production starts.
