What Are Aluminum Washers and Aluminum Pressed Parts?

Aluminum washers are flat, disc-shaped components with a central hole, used to distribute load under a bolt or nut, provide spacing, reduce friction, or act as locking elements. They range from simple flat washers to complex forms including spring washers, tab washers, shakeproof washers, wave washers, and custom profiled washers.

Aluminum pressed parts (stamped parts) are components produced by pressing/stamping flat aluminum sheet or coil through a die to achieve the required shape, hole pattern, embossing, or form. They include: blanked components, pierced parts, drawn parts, bent brackets, formed channels, embossed plates, deep-drawn cups, complex multi-stage stampings, aluminum clips, clamps, covers, shields, spacers, shims, retaining rings, and custom sheet metal components.

What Separates Us from Other Manufacturers

The pressed parts market is crowded with suppliers, but very few can offer genuine in-house tooling capability, a broad alloy range, and global export experience under one roof. We do not purchase tools from third parties and mark them up — we design, build, trial, and maintain all dies in our own tool room. This gives us complete control over tool life, dimensional repeatability, and the ability to modify tooling quickly for design changes or tolerance improvements.

Our global exposure through 30 years of exporting means we understand the documentation requirements of each destination country — CE marking support, UL material compliance, REACH declarations, RoHS certifications, phytosanitary-compliant packaging (ISPM-15) — we have done it all before and handle it without fuss.

We also actively encourage customers to share their annual forecasts so we can pre-plan material procurement and press scheduling, resulting in consistent on-time delivery even during busy periods. This collaborative approach is what builds long-term partnerships.

Flexibility to Customize

Standard DIN or ISO washers are just the beginning. We regularly produce: custom OD/ID combinations, non-round washers (square, hexagonal, D-shaped), slotted hole washers, multi-hole plates, washers with countersinks or countersunk holes, washers with anti-rotation tabs, custom formed gasket blanks, shaped shims and spacers, and complex multi-feature pressed components — all from customer-supplied drawings. Tooling cost is reasonable and quoted transparently. We can turn around tooling trials in as few as 2 weeks for simple washers.

Export-Worthy Packaging

Aluminum washers and pressed parts are susceptible to corrosion from moisture and contact damage during shipping. Our packaging standards:

• Aluminum washers packed in moisture-proof poly bags with VCI inner liner; bags heat-sealed for ocean freight
• Larger pressed parts individually wrapped or layered with interleaving paper
• Inner bags placed in double-walled corrugated cartons with adequate blocking material
• Cartons labelled: part number, alloy, finish, quantity, batch/lot number, customer PO
• Export pallets on ISPM-15 heat-treated timber, stretch-wrapped and steel-strapped
• Material Test Certificates, packing list, and Certificate of Conformity in every shipment

Top Q&A – Aluminum Washers & Aluminum Pressed Parts

Q1: What is the difference between aluminum flat washers and SAE/USS washers?
Flat washers (DIN 125 / ISO 7089) are metric-dimensioned. SAE (Society of Automotive Engineers) and USS (United States Standard) washers follow inch-based standards. We manufacture both series and can identify the correct specification based on your bolt size and application.

Q2: Which aluminum alloy is recommended for aerospace washers?
2024-T3 and 7075-T6 are preferred for high-strength aerospace washers. 6061-T6 is widely used for structural applications. All three are available with proper material certification and traceability.

Q3: Can you make aluminum washers with a specific color anodize?
Yes, colored anodize (black, blue, red, gold, clear) is available on aluminum washers. Hard anodize (silver-grey to black) is available for wear-resistant applications.

Q4: What is the flatness tolerance for standard aluminum flat washers?
Per DIN 125 / ISO 7089, flatness is typically ≤1% of the outer diameter. For precision applications, we can apply additional leveling operations to achieve tighter flatness specifications.

Q5: Can you manufacture aluminum shims to very precise thickness tolerances?
Yes. We manufacture aluminum shim packs in thicknesses from 0.05 mm to 3.0 mm with thickness tolerances as tight as ±0.01 mm using precision-ground tooling and controlled blank preparation.

Q6: What presses do you operate for aluminum pressed parts?
We operate mechanical flywheel presses (5T to 200T), hydraulic presses (up to 400T), CNC turret punch presses, and high-speed progressive die presses — covering blanking, forming, deep drawing, bending, and embossing operations.

Q7: Can you supply aluminum pressed parts to the automotive industry?
Yes, we supply aluminum stampings for automotive applications including heat shields, bracket components, shims, and structural clips. PPAP documentation is available on request for automotive supply chains.

Q8: What is your minimum order quantity for aluminum washers?
For standard sizes, MOQ is 1,000 pieces. For custom tooled sizes, MOQ is subject to the tool investment discussion — we try to keep tooling charges reasonable to allow low-MOQ entry for new customers.

Q9: Do you supply aluminum spring washers or wave washers?
Yes, aluminum spring washers (split lock washers) and wave washers are available in various alloys. These are used where elastic preloading or vibration dampening is required in the assembly.

Q10: Can you supply aluminum gasket blanks for pressure equipment?
Yes. We blank aluminum gaskets from 1100, 3003, and 5052 alloy sheets in custom inner/outer diameters, with bolt-hole patterns, to customer drawings or ASME B16.21 gasket dimensions.

Q11: Are your aluminum washers RoHS and REACH compliant?
Yes. All aluminum alloys we use are RoHS-compliant. REACH declarations and material safety data sheets are provided on request.

Q12: What surface treatments are available for aluminum pressed parts?
As-stamped, deburring, bead blast, type II anodize, hard anodize, chromate conversion coating (Alodine), zinc phosphate, powder coating, and lacquer sealing are all available.

Q13: Can you provide aluminum deep-drawn cups or housings?
Yes, we deep-draw aluminum cups, housings, shells, and containers from alloys 1100, 3003, and 5052. Draw depths up to 150 mm in a single draw (ironing available for tighter wall tolerances).

Q14: What tolerances can you achieve on blanked aluminum pressed parts?
Standard blanking: ±0.2–0.3 mm. Fine blanking: ±0.02–0.05 mm. Progressive die: ±0.05–0.15 mm. Tolerances depend on material thickness, alloy, and die design.

Q15: How do you control dimensional consistency on high-volume washer orders?
We use SPC (Statistical Process Control) with regular sampling during production runs. Die maintenance intervals are scheduled to prevent dimensional drift. First-off and last-off parts from each run are retained in our quality records.

Q16: Can you supply aluminum pressed parts on a Kanban or blanket order basis?
Yes, for repeat customers we accept blanket annual orders with call-off schedules. We pre-produce and hold inventory against blanket orders to ensure rapid dispatch when your call-off is triggered.
