Product Overview

Pyrite (FeS₂) is a cost-effective natural extreme pressure (EP) additive for cutting fluids. With excellent extreme pressure and anti-wear properties, it is specially designed for metal cutting scenarios (turning, milling, drilling, grinding) where high load, high speed and high temperature are involved. It replaces traditional synthetic EP additives with better performance and lower cost, suitable for various metal materials (steel, cast iron, aluminum alloy, etc.).

Core Advantages

Superior Extreme Pressure Protection: Forms a dense lubricating film under high pressure, preventing metal-to-metal contact and tool seizure.
Excellent Anti-Wear Performance: Reduces tool wear and extends service life by 20%–35% compared to conventional additives.
Cost-Effective: Natural mineral material, lower cost than synthetic EP additives (such as molybdenum disulfide).
Good Compatibility: Mixes well with various cutting fluid formulas, no precipitation or stratification.
Improve Workpiece Quality: Reduces cutting friction and heat, avoiding workpiece surface scratches and burns.

Application Scenarios

Widely used in metal cutting processes, including but not limited to:

Heavy-duty cutting of carbon steel, alloy steel, cast iron
Precision machining (milling, drilling, tapping) of non-ferrous metals (aluminum, copper alloy)
Grinding and polishing of mechanical parts
Industrial processing of auto parts, hardware, machinery components

FAQ

Q1: What is the role of pyrite in cutting fluid as an extreme pressure additive? A1: It forms a stable solid lubricating film on the tool and workpiece surface under high temperature and pressure, reducing friction, preventing tool sticking and wear, and improving cutting efficiency and workpiece quality.

Q2: Can pyrite be used in water-based cutting fluids? A2: Yes, it has good water compatibility, no stratification or precipitation, and is suitable for both water-based and oil-based cutting fluid formulations.

Q3: How to control the addition amount of pyrite in cutting fluid? A3: The conventional addition ratio is 2%–6%. For heavy-duty cutting (high load, high speed), it can be appropriately increased to 5%–6%; for ordinary cutting, 2%–3% is sufficient.

📦 Packaging & Storage

Packaging: 20kg composite paper bags (with moisture-proof lining) for small batches, 1000kg bulk bags (with pallets) for large orders, both designed to prevent moisture and leakage during transportation.
Storage: Keep in a dry and ventilated warehouse, avoid direct sunlight and rain. Do not store with strong acids or oxidants. The shelf life is 18 months when unopened; after opening, seal the remaining product promptly.
