Manganese Bronze 6J13 and 6J8 are built for durability and performance. The 13% manganese and nickel content in 6J13 gives it superior strength and corrosion resistance, making it perfect for high-temperature sensors and heating elements in industrial settings. The 8% content in 6J8 offers slightly lower resistivity, ideal for cost-effective applications like resistors and sensors in milder environments. Compared to lower-nickel alloys like CuNi8, both provide better strength and corrosion resistance, while being more affordable than high-nickel alloys like Constantan 6J40.

Their thermal conductivity—33 W/mK (6J13) and 38 W/mK (6J8)—ensures efficient heat transfer, critical for heating systems and sensors. With tensile strengths of 360 MPa (6J13) and 340 MPa (6J8), they’re tough enough to handle mechanical stress. Their low temperature coefficient of resistance (TCR) keeps electrical properties stable from -50°C to 450°C (6J13) or 350°C (6J8), making them ideal for medium-temperature applications. Their excellent corrosion resistance shines in harsh environments like marine or industrial settings, ensuring long-term reliability.
