T2 Red Copper Bars

T2 red copper bar is equivalent
to C11000 Electrolytic Tough Pitch (“ ETP”) Copper by U. S. standard. ETP Copper is known for its high electrical and thermal
conductivity, good corrosion resistance and solderability. T2 red copper is basically pure copper with a 99.9% copper composition and
utilized due to its high electrical conductivity (≥97% IAS, International Annealed Copper Standard) and wide range of fabrication
methods, used in a wide variety of applications across diversified end markets, including electronics and electrical components, power
distribution, telecommunications and other economic sectors across China. T2 red copper has excellent hot workability, with inherent
fabrication qualities readily to be bent, soldered, drilled, peened, riveted and formed to fit almost any design specification.

Pipeline of New T2 Red Copper
Bars - Hard and Soft Connection Copper Bars

In addition to the existing
product portfolio, we have a pipeline of new products, including but not limited to, hard connection copper bars and soft connection copper
bars, that are utilized in electric vehicle battery packs for new energy vehicles.

Starting from the latter half
of 2022, our R& D team has been dedicated to the R& D of hard and soft connection copper bars. In December 2023, we completed the
sample production and testing phase and progressed to the small batch production and testing stage for both hard and soft connection copper
bars.

Copper hard connection bars. Copper
hard connection bars are made of copper bars and refined with design, cutting, bending, drilling and other processes, according to the
assembly space inside the battery pack and technical requirements. This product conducts current and connects electrical equipment within
a circuit. It is typically used in the compact space of a battery pack to function as a conductor. Its insulation is provided by heat
shrink tubing, in-mold injection molding, and similar methods.

Copper soft connection bars. The
copper soft connection bars are constructed by stacking multiple layers of copper foil, each ranging from 0.05 to 0.3 mm in thickness.
These layers are bonded through high-current heating and pressure welding via polymer diffusion welding. The bar undergoes various processes
such as grinding, punching, cutting, polishing, bending, and
