The flame spreader is the component that does the real work in a gas burner — it takes the gas-air mixture and distributes it into a clean, even ring of flame. Because it sits directly in the fire, the material it is made from determines how long it lasts and how evenly it burns. Understanding this material is the key to buying flame spreaders that your customers will not return. Here is what every parts wholesaler should know.
Flame spreaders are cast from a high-temperature aluminum alloy, and for good reason. Aluminum conducts heat quickly and evenly, so the spreader reaches operating temperature fast and delivers a stable flame without hot spots. Crucially, the alloy is formulated to resist the sustained heat of a burner flame without deforming, so the spreader keeps its precise port geometry over thousands of cooking cycles.
Each metal has its place, but for a flame spreader the high-temperature aluminum alloy offers the best balance of performance, durability, and cost.
A poorly cast spreader warps or its ports clog and corrode, producing yellow flames, uneven heating, and customer complaints. A quality aluminum-alloy spreader holds its shape and burns clean for years. When your parts last, your customers reorder from you — and recommend you to others.
