A wire mill in Zhenglu, and nothing else.
XIANYU ALLOY draws precision alloy wire at Zhenglu, Tianning District, Changzhou — a town that has been making instrument materials and alloy wire for the Yangtze River Delta for a long time. Our business is one thing: turning alloy into wire that a customer can put straight onto a production line.
Who we are
We are paid for the drawing, not for the metal.
We do not trade metal and we do not take positions on the nickel price. Material is bought against a confirmed order, priced from the published spot market, and drawn here. What we sell is the conversion: the passes, the anneals and the inspections that turn a rod into a specified wire.
That model keeps the quotation honest. Metal cost and conversion fee are shown on separate lines, and the customer can see which part of the price moves with the market and which part is process.
- Only wire — no trading, no unrelated fabrication
- Metal priced from the published spot market on the order date
- Conversion fee quoted as a separate line item
- Drawing, annealing and inspection carried out in one plant
Background
From an alloy materials works to a fine-wire plant.
1990
Drawing starts at Zhenglu
The business traces back to the Wujin electronic alloy materials works at Zhenglu, which began drawing alloy wire in 1990 for the instrument and thermocouple sector of the Yangtze River Delta.
2012
Present company registered
The drawing operation was registered as a separate company, keeping the drawing floor, the staff and the specification knowledge of the original works.
Today
Six families, 0.025 – 6.00 mm
Pure nickel, Monel 400, constantan, manganin, copper-nickel resistance alloys and thermocouple wire, drawn from in-house melted stock, with export documentation prepared for overseas customers.
Plant & equipment
What is actually on the floor.
The list below is the installed equipment base, which supports an annual output above 100 tonnes. It is deliberately weighted towards fine-wire drawing: four fine drawing lines against one coarse and one intermediate line.
| Process stage | Equipment | Units | What it does |
|---|---|---|---|
| Melting | Vacuum melting furnace | 3 | Alloy melting and composition adjustment before drawing |
| Drawing | Coarse drawing machine | 1 | First reduction passes from rod |
| Drawing | Intermediate drawing machine | 1 | Mid-range reduction |
| Drawing | Fine drawing machine | 4 | Fine and ultra-fine passes down to 0.025 mm |
| Finishing | Straightening machine | 2 | Straightness and coil set control |
| Heat treatment | Box annealing furnace | 3 | Temper control for soft / half-hard / hard condition |
| Heat treatment | Pit annealing furnace | 1 | Larger-batch and long-length annealing |
| Inspection | Tensile testing machine | 2 | Tensile strength and elongation |
| Inspection | Resistance-per-metre meter | 1 | Electrical resistance verification for resistance alloys |
| Packing | Rewinding machine | 1 | Transfer to customer spools and coils |

The town matters more than you might expect.
Zhenglu and the neighbouring townships form one of China's densest clusters of instrument-material and resistance-alloy producers. In practice that means dies, lubricants, spool makers and experienced drawing hands are all within a few kilometres — and it means our customers can measure us against the best plants in the cluster.
Scope
What we do — and what we decline.
Drawing to specification
- Round wire from 0.025 mm to 6.00 mm
- Soft (M), half-hard (Y2) and hard (Y) tempers
- Matched positive/negative thermocouple legs
- Toll drawing — customer supplies the material
- Non-standard diameters, spool sizes and labelling
Things outside the drawing floor
- Metal trading or speculative stocking
- Heavy commodity rod at tonnage scale — better served by a large mill
- Assembled temperature sensors or finished instruments
- Co-extruded or clad products
If your requirement is outside the list on the left, we will say so rather than quote for something we cannot hold to specification.

Send the grade, diameter, temper and quantity. If the specification is still open, describe the application and we will suggest a starting point.
