Copper,specifiedto the micron.
Strip, sheet, rod, tube, busbar and brass for manufacturers who cannot afford variation. Tell us the grade, size, tolerance and destination. We answer with a quote you can compare line by line.
International procurement is a chain of small promises. We make each one visible: what was specified, what was tested, what was packed, and when it will arrive.
Specify it once.
Quote it right.
Most quote delays come from one missing detail. Pick the form, grade and size below. The spec sheet fills itself in, and you can send it to Serena on WhatsApp or by email with one tap.
Serena from our sales team usually replies within a few working hours (China time, UTC+8). Drawings can follow in the same chat.
Choose the form
your line needs.
From precision slit coil to custom profiles. Click any material to load it into the spec builder.
One alloy.
Four names.
Your drawing says C11000. Our mill sheet says T2. Here is how the common designations line up, with typical conductivity, so engineering and purchasing are talking about the same metal.
This table is a reference for discussion, not an automatic substitution. Chemistry, conductivity, mechanical properties and temper must be checked against the governing standard on your drawing before an order is released. Conductivity values are typical annealed figures.
What the lab
actually recorded.
Results from Junkai Copper's internal material reports, translated into English. Customer names and order identifiers are removed.
These are sample records, not independent product certifications or order certificates. Ask whether your MTC or COA covers a sample or the supplied batch.
From a drawing
to a delivered lot.
Six checkpoints, each with something you can see or sign off. Scroll through the journey of one order.
You send the brief.
Material, grade, size, quantity, destination. A drawing or a previous mill certificate is even better. Short is fine.

We confirm before we quote.
Grade and governing standard, temper, tolerance, surface and edge condition. Questions come first, so the price you get is the price for what you need.

Rolled, drawn, slit to width.
Material is processed to the agreed format: slit coil, cut lengths, straight tube or pancake coil, rod or custom profile.

- Cut-to-length
- Custom profiles
Measured and recorded.
Dimensional and surface checks, plus chemistry or mechanical results where the order requires them. MTC or COA on request.

Materials that earn
their place in the line.
Electrical
Busbar, connectors and switchgear where conductivity is the spec.
HVAC & refrigeration
Tube and pancake coil for heat exchangers and refrigerant lines.
Automotive
Strip for stamping terminals and rod for cold heading where repeatability matters.
Architecture
Copper and brass sheet with finish-ready surfaces that age with character.
What should be
clear before
a quote?
Which details belong in a copper or brass RFQ?
Product form, grade or standard, dimensions, tolerance, temper, surface or edge condition, quantity, application, destination and drawing revision. The spec builder above covers all of them.
Are you a factory or a trading company?
Both. We process copper strip, tube and related products in our own Shandong facility, and we also source specific alloys and formats through partner mills, so one contact can cover a mixed order.
How should I compare grade references?
Use the designation and governing standard on your drawing or a previous certificate. Chemistry, conductivity, mechanical properties and temper are reviewed together. A reference table is not an automatic substitution.
Which documents can come with the order?
MTC or COA on request, plus dimensional or inspection records, labels and packing details. Confirm whether a document covers a sample or the supplied batch.
Do you ship to the Middle East and Central Asia?
Yes. Sea freight to Gulf ports such as Jebel Ali, Dammam and Jeddah, and rail or multimodal routes toward Kazakhstan and Uzbekistan. Terms are FOB, CFR or CIF, confirmed per order.
What is the minimum order?
It depends on the form and grade. Stock sizes can go small, while custom widths or profiles need a production lot. Send your quantity and we will tell you straight away.
