Product Formation

The all-copper direct current (DC) spray fire water gun is a high-end fire-fighting equipment centered on all-copper materials. Through a product development logic of "material optimization + structural refinement + function integration", it breaks through the limitations of traditional fire water guns in corrosion resistance, thermal conductivity, and durability, and is specifically designed for harsh fire scene environments (e.g., chemical leaks, high-temperature exposure, high-salt-spray corrosion scenarios).

Its product development revolves around three core principles: material purity, functional reliability, and environmental adaptability. From material selection to process implementation, it achieves deep integration of the "all-copper gene" and "DC spray function."

It is not merely a "material upgrade"—but more critically, a performance leap. It has become a benchmark for high-end fire-fighting equipment in harsh scenarios (chemical plants, marine environments, high-temperature areas), combining efficient firefighting, long-term reliability, and safety stability. Ultimately, it represents the trend of modern fire-fighting equipment toward "material specialization and functional refinement".

Product Features

Exceptional Corrosion Resistance for Harsh Environments: Crafted from 99.9% copper (purple copper/brass alloy), it is inherently immune to salt spray, acid, and alkali corrosion. It passed the 1000-hour salt spray test (GB/T 10125-2021) without rust—boasting over 3× better corrosion resistance than aluminum alloy models. Designed for chemical leak scenarios (chlorine/ammonia corrosion), marine high-salt-spray environments (ship cabins, ports), and industrial exhaust-laden spaces, it eliminates failures from material rust (e.g., leakage, jamming) and slashes maintenance costs.
Superior Thermal Conductivity for High-Temperature Reliability: Copper’s thermal conductivity (401W/m·K) is nearly twice that of aluminum alloy (205W/m·K). When exposed to 800℃ flames, the gun’s surface temperature remains below 150℃ (vs. ≥220℃ for aluminum alloy), preventing thermal deformation. In high-heat settings like steel mills or refineries, it maintains structural integrity—ensuring firefighter safety during close-quarters operations.
High Structural Strength for Doubled Durability: The all-copper body uses an integral casting process (no welded joints), with tensile strengths of 220–250MPa (purple copper) and 300–400MPa (brass). It withstands a burst pressure of ≥4.8MPa (3× the safety factor under 1.6MPa working pressure). With an 8–10 year lifespan—60% longer than aluminum alloy models (5 years)—it reduces the logistical burden of frequent equipment replacement.
DC Mode: Stable Long-Range Attack Performance: Equipped with a precision-turned brass DC nozzle, it features an internal spiral flow guide cone and convergent flow channel—boosting water compression ratio by 15%. It delivers a range of 25–45 meters (35 meters at 1.0MPa pressure). The smooth copper inner wall (roughness Ra≤0.8μm) ensures flow error ≤5%, enabling precise targeting of high-rise window fires or localized equipment blazes.
Precision Manufacturing for Minimal Performance Decay: The body undergoes lost-wax casting + CNC precision machining, with key components toleranced to ±0.05mm. The internal water channel is electrolytically polished (Ra≤0.6μm) to reduce scale adhesion—resulting in negligible jet performance degradation even after prolonged use.
