A Spark That Never Fails

From Formula 1 racetracks to freezing Himalayan mornings, engines around the world rely on one consistent miracle — a spark. That spark starts with DOMADIA™ NiMn2Cr, a scientifically engineered alloy built to resist extreme conditions while delivering reliable performance in ignition systems.

Whether it’s a gasoline spark plug or a diesel glow plug, NiMn2CrSiTiZr is the go-to solution for manufacturers who want performance without compromise.

What is DOMADIA™ NiMn2Cr?

DOMADIA™ NiMn2Cr is a Nickel-Manganese based alloy enriched with Chromium (Cr), Silicon (Si), Titanium (Ti), and Zirconium (Zr). Its advanced composition gives it excellent resistance to oxidation, rapid thermal cycling, and mechanical fatigue. Perfectly suited for spark plug and glow plug manufacturing, it is part of a select class of electrical-grade ignition alloys.

Chemical Composition: NiMn2CrSiTiZr

This combination results in a fine-tuned alloy ideal for high-energy ignition environments.

Applications of NiMn2CrSiTiZr

DOMADIA™ NiMn2Cr thrives in applications demanding extreme reliability:

• Automotive Engines: Spark plugs are essential in gasoline-powered vehicles to ignite the air-fuel mixture. 
• Motorcycles: Spark plugs are vital for efficient combustion in motorcycle engines. 
• Small Engines: From lawnmowers to generators, small engines rely on spark plugs. 
• Aircraft Engines: Spark plugs are used in some aircraft engines for ignition. 
• Marine Engines: Spark plugs are used in outboard motors and other marine engines. 
• Furnaces and Other Applications: In certain industrial and domestic applications, spark plugs are used to ignite combustible mixtures. 
• Spark Plugs – Ensures reliable ignition in gasoline engines
• Glow Plugs – Assists in diesel engine starting under low temperatures
• Heater Elements – Where fast heating and durability are needed
• Electrical Resistors – Due to stable resistance over temperature
