tungsten rhenium alloy wire
Dimension
Diameter, um | Weight of 200mm, mg tungsten wire in spool | Length, min |
20<d ≤ 60 | >0.44-10.91 | 700 |
60 < d ≤ 100 | >10.91-30.30 | 400 |
100<d ≤ 150 | >30.30-68.18 | 250 |
150<d ≤ 200 | >68.18-121.20 | 150 |
200<d ≤ 350 | >121.20-371.19 | 100 |
350<d ≤ 700 | - | as the length of 150g |
700<d ≤ 1800 | - | as the length of 200g |
Note: Your special request for 0.02mm silver tungsten wire will be available.
The deviation of diameter and weight:
diameter, d, um | weight of 200mm mg | weight deviation of 200mm, % | diameter deviation, % |
I | II | III | I | II | III |
20<d≤40 | >0.98-4.85 | ±2.0 | ±2.5 | ±3 | - | - | - |
40<d≤80 | >4.85-19.39 | ±1.5 | ±2.0 | ±2.5 | - | - | - |
80<d≤300 | >19.39-272.71 | ±1.0 | ±1.5 | ±2.0 | - | - | - |
300<d≤350 | >272.71-371.19 | | ±1.0 | ±1.5 | - | - | - |
350<d≤500 | - | - | ±1.5 | ±2.0 | ±2.5 |
500<d≤1800 | - | - | ±1.0 | ±1.5 | ±2.0 |
Note: When diameter over 20-250um, the weight deviation of every 200mg wire should not more
than 1/2 of the same level. When diameter over 250-300mm, the weight deviation of every 200mg
wire should less than 1/2 of II deviation.
