FAQ's

Question & Answer

What does DELCO manufacture?: DELCO manufactures aluminium circles (Alloy 1050 & Alloy 3003), hard-anodised (HA) circles, non-stick cookware circles, brazed/impact-bonded circles, and medical circles such as those used in autoclaves and surgical trays.
Which aluminium circles do you supply?: We supply Alloy 1050 and Alloy 3003 as standard, plus other commercial-purity aluminium grades for cookware, medical and industrial circle production.
What are HA circles (hard-anodised circles)?: HA circles are aluminium circles that have undergone hard anodising to create a dense, wear-resistant, corrosion-proof surface ideal for cookware and medical applications.
Why choose hard-anodised (HA) coating?: Hard anodising increases surface hardness, corrosion protection and wear resistance while improving heat performance and coating adhesion — perfect for cookware and long-life circles.
What coating specs do you offer for hard anodising?: HA coating thickness typically ranges from 10–50 µm. We control every step — thickness, sealing, post-treatment — and supply data on micro-hardness and uniformity for every circle batch.
Can you match anodised colour and finish across batches?: Yes. We perform spectrophotometric checks and sample approvals to ensure consistent HA circle colour and finish across production lots.
Are hard-anodised circles safe for food contact?: Properly processed HA surfaces form a stable oxide layer widely used in cookware. We can share data sheets confirming food-contact safety.
Do you apply non-stick coatings on HA or raw circles?: Yes. We apply PTFE/PFOA-free non-stick systems directly on HA or untreated aluminium circles with controlled pre-treatment for durable adhesion.
Do you provide hydrogen analysis and metallography?: Yes — batch hydrogen, metallography and adhesion tests are performed to ensure drawability and HA coating quality on every circle batch.
What thicknesses and diameters are available?: We produce thin- to medium-gauge circles (approx. 0.3 mm – 6 mm) in custom diameters. HA circles can be supplied to exact OD/ID and coating-thickness specs.
Do you make circles for autoclaves and surgical trays?: Yes — we manufacture aluminium circles for medical use such as autoclave shells, sterilization trays and surgical accessories, with full QC traceability.
What is your lead time?: Sample HA or plain circles: 7–14 days. Production: 3–6 weeks. Lead time may vary with coating thickness and quantity.
What is the minimum order quantity (MOQ)?: MOQ depends on size and finish — smaller lots for plain circles, higher for HA or medical grades. Send details for a quick quote.
What quality documents do you supply?: Each shipment includes material certificates, hydrogen analysis, dimensional and coating-thickness reports. Medical-grade circles include traceability records.
Do you export aluminium circles?: Yes — DELCO exports HA and plain circles worldwide under EXW, FOB or CIF terms. We help with documentation and logistics.
What sustainability practices do you follow?: We recycle aluminium scrap, use energy-efficient anodising, and minimise wastewater in HA lines.
