2115: Is powder coating allowed?


99319B
2-Sep-2024

According to R16b. heat treating of metal elements is not allowed. I have a team that wishes to powder coat their metal parts for decoration. Is this allowed as part of the powder coating process includes baking the part in a 350-400 degree F oven or is this considered heat treating per the game manual?

<R16> Most modifications to non-electrical components are allowed. Physical modifications, such as bending or cutting, of legal metal structure or plastic components are permitted.

b. Metallurgical modifications that change fundamental material properties, such as heat treating or melting, are not permitted.<R16>

EDIT: After further research Vex Aluminum is 5052-H32 This type of aluminum is not heat treatable. I am going to assume that powder coating is therefore allowable unless otherwise noted by committee.

Aluminum 5052 H32

Aluminum 5052 H32 is a high-strength, non-heat-treatable alloy that offers excellent corrosion resistance, good weldability, and formability. The H32 temper designation signifies that the material has been strain hardened and stabilized, resulting in improved strength and workability. It has a smooth, shiny surface and is often used in sheet metal applications where strength and durability are required.

Aluminum 5052 H32 is commonly used in the manufacturing of sheet metal parts for the automotive, aerospace, and marine industries, as well as in construction and architectural applications. It is also used in the production of cooking utensils, electronics, and packaging materials due to its excellent corrosion resistance and non-toxic properties.

FastMetals currently offers Aluminum 5052 H32 in sheet products. The 5052 sheet product is available in a variety of thicknesses and sizes, and is commonly used in the manufacturing of sheet metal parts.

The heating process required to cure powder coating should not change the fundamental material properties of the V5 metal, so powder coating V5 metal structure is allowed.

However, parts that are painted, coated, or otherwise obscured may be subject to additional scrutiny during Robot inspection to confirm their legality for competition use.

Note: As of October 1, 2024, anodizing or color changing of parts (such as painting/painting, etc., which changes the original appearance of parts) is no longer allowed in events in mainland China.
