Composition Nickel (Ni) – 60.5%, Chromium (Cr) – 23%, Aluminum (Al) – 1.4%, Iron (Fe) – 14%
Melting Point 2,615°F (1,435°C)
Density 0.297 lb/in³ (8.22 g/cm³)
Tensile Strength 90 ksi (620 MPa) at room temperature
Yield Strength 35 ksi (240 MPa) at room temperature
Elongation 40% at room temperature

As you can see, Nickel Alloy 601 Powder is primarily composed of nickel, chromium, and iron, with small amounts of aluminum and other trace elements. This carefully crafted composition gives the alloy its exceptional properties, including high-temperature strength, oxidation resistance, and corrosion resistance.

Nickel Alloy 601 Powder Composition and Properties

The unique composition of Nickel Alloy 601 Powder is what sets it apart from other alloys. Let’s take a closer look at the key elements and their contributions:

Element Percentage Contribution
Nickel (Ni) 60.5% Provides high-temperature strength, oxidation resistance, and corrosion resistance
Chromium (Cr) 23% Enhances corrosion resistance and oxidation resistance at high temperatures
Aluminum (Al) 1.4% Improves oxidation resistance and strength at high temperatures
Iron (Fe) 14% Adds strength and reduces cost

Nickel, the primary element, is responsible for the alloy’s exceptional high-temperature strength and resistance to oxidation and corrosion. Chromium further enhances these properties, particularly at elevated temperatures. Aluminum plays a crucial role in improving oxidation resistance and strength at high temperatures, while iron contributes to the overall strength and helps reduce the cost of the alloy.

But it’s not just the composition that makes Nickel Alloy 601 Powder so remarkable. Its unique properties, such as a high melting point of 2,615°F (1,435°C), excellent tensile strength, and good elongation, make it suitable for a wide range of demanding applications.
