Company scope
What the company makes
Zhejiang Tony Electronic Co., Ltd. is the English name its 2025 annual report gives for 浙江东尼电子股份有限公司. The company traces its start to 2008 and its Shanghai listing to 2017. It makes materials for consumer electronics, medical products, new-energy vehicles, photovoltaics and semiconductors. For solar buyers the relevant product is finished diamond cutting wire: diamond particles fixed onto a carbon-steel or tungsten core and run on a slicing machine to cut single- and multicrystalline silicon. Bare core wire, automotive conductors, medical cable and SiC substrates belong to other Tony businesses.
The product page gives steel cores of 36–42 μm and tungsten cores of 24–28 μm, each with 5–8 μm diamond particles. Those diameters refer to the core alone. Tony publishes no finished-wire outer diameter and no list of stocked grades, so both belong in your request for quotation.
Tony's 2025 report on CNINFO names the company and its diamond-wire business, and it says diamond-wire production fell substantially during that year. Ask which grades are available now, where they are made and when samples can ship. Tony promotes its wire for thin wafers and low breakage; a slicing trial on your own saw and silicon puts numbers on those points.

Steel-core and tungsten-core diamond cutting wire →
Tony's diamond cutting wire carries 5–8 μm diamond particles on a carbon-steel core of 36–42 μm or a tungsten core of 24–28 μm. It runs on a slicing machine to cut mono- and multicrystalline silicon wafers. Order it as coated finished wire,… [2]
Specifications & selection questions →Tony product data
Tony steel-core and tungsten-core diamond wire side by side
| Family | Core diameter | Diamond particle size | Ask for with the quote |
|---|---|---|---|
| Steel-core diamond wire | 36–42 μm | 5–8 μm | Exact size, spread of finished-wire diameters, coating and spool specification. |
| Tungsten-core diamond wire | 24–28 μm | 5–8 μm | Exact size, tensile test data and fit with your slicing machine. |
Tony publishes a range for each family. Stocked combinations, wafer thickness, kerf and breakage rate have to come from Tony for your specific order. [2]
Order coated wire by name
Say in the enquiry that you want finished, diamond-coated cutting wire. A core diameter on its own could describe bare wire, so ask for the coating, the diamond size distribution and the delivered spool to be stated in the quote. [2]
Putting numbers on performance
Testing Tony's thin-wafer and low-breakage claims on your own saw
Describe the silicon
State mono or multicrystalline, block geometry, target wafer size and thickness, and your quality limits. Tony also lists other hard brittle materials, and results on those say little about silicon. [2]
Share the saw setup
Give Tony your saw model, guide system, winding and spool needs, coolant route and planned process, and ask for the mechanical limits of the exact wire on offer. The product page gives no figures for tension, wire speed or feed. [2]
Compare like with like
Log breakage, wafer quality and wire consumption with the same silicon and process settings you use for your current wire. Tony's wording on speed, wear and low breakage gives you the points to measure in that comparison. [2]
Manufacturing chain
Who draws the core, applies the coating and checks each lot
Tony's in-house chain
Tony describes an integrated tungsten chain, its own equipment development and quality control from raw material to finished product. Ask which company draws the core, coats it and runs final inspection for your wire, and whether any step goes to a subcontractor. [2]
Strength and coating records
Request core and finished-wire dimensions plus breaking force and elongation, each with its test conditions. Ask separately how particle distribution, coating uniformity and particle retention are controlled. Company awards sit apart from these lot-level records. [2]
Spool and shipment
Fix the wire length, spool shape, winding direction, usable ends, lot labels, packing and storage conditions. Settle which documents travel with each shipment and how damaged or out-of-spec wire gets investigated. Spool dimensions have to come from Tony in writing, since the product photo carries none. [2]
Availability today
Checking Tony's current diamond-wire supply before you plan around it
Name the wire you want
Send core material and exact size, abrasive needs, workpiece and saw setup. The reply should tell you whether Tony offers a standard grade or proposes a custom development. [2]
Ask about output and lead time
The 2025 annual report records a substantial fall in diamond-wire production. Ask for current availability, the producing site, lot size and a delivery schedule Tony will commit to. Past production totals tell you little about spare capacity for an order placed today. [3]
Approve samples
Set the sample quantity, test conditions and the dimensional, mechanical and cutting records you expect back. Keep your baseline fixed while you change wire material or size, and plan to witness the cutting trial yourself. [2]
Reach the sales side
Tony's website lists an enterprise phone line and an investor mailbox. The mailbox serves shareholders, so ask for a named contact for PV wire sales. [1]
Project fit
Match the offering to your project
Silicon wafer plants qualifying finished steel-core or tungsten-core diamond cutting wire.
Buyers who want to compare Tony's two core ranges on a fixed saw and workpiece setup.
Consumable purchasing that needs coating, spool and lot paperwork; complete saw specifications are outside Tony's offer here.
Confirm before ordering
- The exact grade or SKU, finished-wire outer diameter, size tolerance, spool dimensions and guaranteed length.
- Breaking force, tension limit, feed and speed window, kerf, wafer thickness and a breakage rate from a witnessed trial.
- Current order availability, the company that signs the contract and a named sales contact.
Facts on Tony come from its company and diamond-wire pages and from the 2025 annual report it filed on CNINFO.

Continue to sourcing requestBuyer questions
Is 24–28 μm the outer diameter of Tony's tungsten wire?
Tony labels it as the core diameter. Ask for the finished-wire size and the coating distribution in writing. [2]
Will the thinner tungsten core give me thinner wafers?
Tony publishes no wafer-thickness figure or trial method. Your saw, silicon, process and acceptance limits decide the outcome, so plan a qualification run. [2]
What does the annual report say about supply?
It is a dated company filing that records lower diamond-wire production in 2025. Ask Tony for today's availability and the producing and shipping route. [3]
