Copper Needle tubes, Copper Needle Tube Manufacturer,Copper Needle Tube Supplier, Copper Needle Tube Exporter,Copper Precision Tubing, Copper Small Diameter Tube ,Copper Needle Tubes
Sumer Metal Industries Private Limited manufactures precision Copper Needle Tubes engineered for applications that demand high conductivity, corrosion resistance and tight dimensional tolerances. Our copper needle tubes are cold-drawn and annealed (where specified) to provide excellent surface finish and concentricity, making them ideal for instrumentation, refrigeration capillaries, medical devices, HVAC components and precision fittings. Production is carried out in ISO-aligned facilities with dedicated drawing and polishing lines to ensure consistent quality from prototype lots through high-volume runs.
As a supplier and exporter, Sumer Metal Industries ships Copper Needle Tubes globally — with established export relationships across Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple regions across Africa. We tailor exports to meet local standards, supply-chain requirements and commercial packaging preferences, offering cut-to-length, coiled or kitted deliveries. Our export documentation and third-party inspection options (e.g., Mill Test Certificates, third-party chemical/physical testing) support international procurement and customs procedures.
Quality control is central to our offering. Every batch of copper needle tube is inspected for dimensional accuracy (OD/ID/wall), surface finish, straightness and internal cleanliness. We employ optical measuring systems, micrometers, air-pressure leak tests (when required) and destructive test sampling for mechanical verification. Surface finishes are supplied as bright-drawn, polished or tinned/treated on request for solderability or enhanced corrosion resistance. Traceability is maintained from melt/coil to final shipment.
Technically, our copper needle tubes are provided in common commercial copper grades (selected to match the application) and can be supplied in various tempers — annealed, half-hard or full-hard — depending on bending and forming needs. Standard chemical compositions and mechanical properties are offered as typical ranges in the specification tables below; for critical projects we provide test certificates and can manufacture to customer-specified chemistries and tolerances, including oxygen-free variants for electronic or vacuum applications.
Specification of Copper Needle tubes
| Item | Typical Value / Options |
|---|---|
| Material Grades | Commercial copper grades such as C11000 (ETP), C10100 (Oxygen-Free Copper) — custom grades available on request |
| Production Method | Cold-drawn seamless tube (single or multi-pass drawing) |
| Surface Finish | Bright-drawn, polished, tinned (optional), cleaned and oiled for export |
| Tempers | Soft (annealed), half-hard, full-hard |
| Tolerances | OD tolerance ±0.02 mm to ±0.10 mm depending on size & specification |
| Lengths | Cut-to-length (mm) / Coils / Reels / Custom kits |
| Certification | MTC (EN/ASTM style), third-party inspection available |
Typical uses include capillary tubes in refrigeration and thermostatic controls, precision tubing for medical needles and delivery systems (non-implant), fuel and hydraulic instrumentation, and signal or sensor feed-throughs where small-bore, mechanically stable tubing is required. Because copper offers excellent thermal and electrical conductivity, it is also widely used where heat-transfer or grounding is required in a compact form factor. Our engineering team supports customers with material selection and forming advice to maximize yield and reduce downstream rework.
Chemical Composition of Copper Needle tubes
| Element | Typical (%) |
|---|---|
| Copper (Cu) | ≥ 99.90 |
| Oxygen (O) | ≤ 0.04 |
| Phosphorus (P) | ≤ 0.005 |
| Impurities (Fe, Pb, Zn, Ni, Sn, etc.) | ≤ 0.05 (total) |

❓ Frequently Asked Questions (FAQs)
Q1: What copper grades are available for needle tubes?
A1: We commonly supply copper needle tubes in commercial grades such as C11000 (ETP) and C10100 (oxygen-free copper). Special chemistries and certified alloy variants can be produced on request to meet application-specific requirements.
Q2: What tolerances and surface finishes can you provide?
A2: Typical OD tolerances range from ±0.02 mm to ±0.10 mm depending on size and order volume. Surface finishes include bright-drawn, polished and optionally tinned for improved solderability; custom finishes can be arranged.
Q3: Do you export and provide test certificates?
A3: Yes — Sumer Metal Industries exports to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions across Africa. We supply Mill Test Certificates (MTC) and can arrange third-party inspection and additional documentation required for customs and quality assurance.
