About Phenolic Canvas Electric|Canvas-reinforced phenolic laminate with electrical-grade properties. Good dielectric strength for moderate voltage applications. Used for electrical switchgear components, panel boards, and insulators. Compare to Phenolic Canvas (mechanical grade) and G-10/FR-4 (better electrical properties, more expensive).
About Plate|Thick flat stock, generally 3/16" and up, used for machined base plates, fixture plates, wear surfaces, and structural fabrication. Heavier grades get milled, drilled, and tapped directly.
