Alliage de fonderie d'aluminium A380

Linsy A380 is the most widely specified aluminum-silicon-copper die casting alloy. It combines excellent castability, good mechanical properties, and economic pricing, with resistance to stress-corrosion cracking and reliable dimensional stability in complex, thin-walled parts. A380 is normally used in the as-cast (F) condition without further heat treatment, though T5 is sometimes applied for added stability.

Propriétés mécaniques selon le traitement thermique

The values below are typical room-temperature properties for the indicated condition and should be confirmed against mill test data for your specific casting and heat treatment. Casting method, section thickness, and cooling rate affect results.

Tempérer Résistance à la traction (MPa) Limite d'élasticité (MPa) Élongation (%)
F (as-cast) 310–340 155–165 3.0–4.0
T5 310–340 160–180 2.5–4.0

Guide de sélection des tempéraments

Choose the temper based on your priority between strength, ductility, and dimensional stability:

Tempérer When to Use
F (as-cast) As-cast, no heat treatment. Best economy and dimensional stability for die and sand castings.
T5 Artificially aged only (no solution treatment). Improved strength with lower cost and distortion than T6.

Key Characteristics of A380 Aluminum

Excellent Castability

High silicon and copper give A380 superior fluidity and filling of thin, complex dies at high production rates.

Good Strength & Stiffness

Among the strongest common die-cast alloys, A380 suits load-bearing brackets and housings.

Stabilité dimensionnelle

Low tendency to warp or shrink supports tight-tolerance high-volume production.

Applications courantes

  • Automotive components (oil pans, brackets)
  • Electrical and electronic chassis
  • Power tool housings
  • Household appliances
  • Furniture and lawn mower parts

Remarques concernant le traitement et la finition de surface

A380 is normally die cast and used as-cast. Machining, tapping, and vibratory finishing are standard. Plating and powder coating are common; anodizing is limited by the high silicon content and is not typically recommended. Welding is generally avoided for structural die-cast A380.

Documents relatifs à la qualité et contrôle qualité

Every A380 shipment is delivered with an MTC (material test certificate) covering chemical composition and mechanical properties as ordered. Dimensional inspection and third-party verification (e.g. SGS report, available on request) can be arranged. Our production system is managed under ISO 9001, ISO 14001, and ISO 45001.

A380 Aluminum FAQ

A380 vs A383 — which to choose?

A383 has higher silicon and better fluidity plus improved hot-cracking resistance, preferred for very intricate or thin-wall dies. A380 offers slightly better strength and is the general default.

Is A380 heat treated?

Usually no — it is supplied as-cast (F). T5 may be used where added dimensional stability is required.

FAQ générale sur les commandes

What is the typical lead time for casting alloy orders?

For standard ingot and common sand/permanent-mold castings, typical lead time is 10–60 days depending on temper, quantity, and any required machining or surface finishing. Confirm exact timing with our sales team when requesting a quote.

Do you provide mill test certificates (MTC)?

Yes. Every shipment is supplied with an MTC (material test certificate / inspection report) covering chemical composition and mechanical properties as ordered.

Can Linsy supply custom casting sizes and tempers?

We support custom dimensions, casting method selection, heat treatment (F, T4, T5, T6 as applicable), and downstream CNC machining, polishing, and anodizing. Share your drawing or spec and we will quote against it.

Which standards do your casting alloys meet?

Our casting alloys are produced and inspected against widely recognized standards such as ASTM B26/B85 and EN 1706. Specific designation cross-references are listed on each product page; confirm the exact standard requirement for your market when ordering.

How should I request a quote?
