Industrial Pure Iron 50-50HV
Purpose：Industrial pure iron is a type of steel primarily composed of iron (99.50%–99.90%) with carbon content below 0.04%. Though not entirely pure iron, it is classified as such due to its near-pure composition. Industrial pure iron is exceptionally soft, highly ductile, and exhibits excellent electromagnetic properties. Common applications include: 1.Deep-drawing material: Capable of being stamped into highly complex shapes. 2.Electromagnetic material: Offers high magnetic permeability and low magnetic resistance.
Basic Guide：
Cutting：1.Use an A30 alumina abrasive cutting wheel for industrial pure iron. Refer to the Trojan Cutting Guide for specific models.
2.Select non-pulse mode for cutting, with a recommended maximum cutting speed ≤0.25 mm/s.
Mounting：Use either hot or cold mounting resin, with a preference for hot mounting.
Grinding：1.Begin with P400 silicon carbide sandpaper until the sample surface is flat and cutting damage is fully removed.
2.Continue fine grinding with GF White Synthetin Silk Polishing Cloth + 9 µm PD-WT polycrystalline diamond polishing suspension.
3.Clean the sample, sample holder, and hands after each grinding step.
Polishing：1.Clean the polishing cloth, sample holder, and hands before polishing. Repeat cleaning after each step.
2.Do not mix polishing disks with different abrasive particle sizes.
3.Rinse the sample surface with alcohol and dry with a blower to remove water residue.
4.After each polishing step, inspect under a metallographic microscope to ensure scratch size matches the abrasive grit and direction is random.
5.Clean polishing cloths with running water and a soft brush after use, then air-dry.
6.Dedicate polishing cloths used for pure iron exclusively to iron samples.
