Brass & Copper
Selection of cutting fluid for brass and copper alloy
Has your brass/bronze/copper get discolored during machining? You have to check your cutting oil first. As a manufacturer of cutting oils, we understand that cutting fluids are generally compounding mineral oil and multi additives to stable pH level, lubricity. However, sulfur and chlorine compounds, sometimes called extreme pressure (EP) additives, provide for even greater lubricity. But, they are not suitable for each metal materials.
coolant get color change
Most brasses, bronzes, and copper are stained when exposed to cutting oils containing active sulfur and chlorine. Some formula (additive) has reacted with oxygen, water, and carbon dioxide in the sump, when machining copper and brass. Thus, sulfurized and sulfochlorinated oils should not be used.
Besides, lubricity and cleaning are also most important things. If your cutting oils do not have enough lubricity, metal chips will stick on tools, and even scratch the workpieces. If the chips settled in the sump, no filtered immediately, it will caused oxidize. That is why the coolant form that same patina in the sump....
Hai Lu Jya He recommend MORESCO NN-254T and MORESCO NN-205T neat cutting oils with non-active sulfurized. For water-based cutting fluid, we recommend MORESCO BS-6S semi-synthetic cutting oil and WILL AIE-73 semi-synthetic cutting oil without chlorine additives. These cutting oils are especially good on brass, and provide excellent performances during machining.
