How high a temperature can Candle Tin Cans withstand

The heat resistance of Candle Tin Cans is closely related to its material, thickness and usage scenario, as shown below:
Material and temperature resistance differences
1. Tin-plated thin steel plate (tinplate):
The main body is low-carbon steel (melting point is about 1400℃), but the melting point of the surface tin layer is only 232℃. When used as a candle container, the local temperature near the flame can reach 200~250℃, which may cause the tin layer to melt slightly (the bottom is gray), but the can structure remains intact. For long-term use, it is recommended to have a temperature resistance of ≤120℃ to avoid continuous heat to the tin layer affecting the sealing.
2. Aluminum alloy cans:
The melting point is about 600℃, but the common wall thickness is only 0.2~0.5mm, and the thermal conductivity is strong. When burning continuously, the temperature of the can body is about 80~120℃, and extreme empty burning may rise to 180℃, causing slight deformation of the bottom. The safe temperature resistance is recommended to be ≤200℃ to avoid long-term high temperature affecting the material strength.
3. Stainless steel cans (such as 304):
The melting point is as high as 1398℃. When the wall thickness is 0.3~1mm, it can withstand high temperatures of **300~400℃** without melting. Only the surface is oxidized and discolored. It has the best temperature resistance and is suitable for scenes requiring high temperature environments (such as outdoor heating).
Safety Tips
1. Avoid too little wax (<1/3 of the can volume) or empty burning to prevent local overheating at the bottom;
2. The outer printing ink is resistant to a temperature of ≤120℃, and it is easy to fade or peel off at high temperatures;
3. The inner wall coating (such as epoxy resin) is resistant to a temperature of about 150~200℃. Overheating may release harmful substances, so pay attention to temperature control.
