Brass Inner Cap For Photovoltaic Inverter DC Side Protection

1.The main characteristics of Brass Inner Cap for Photovoltaic Inverter DC Side Protection:

(1)Ordinary Inner End Cap brass has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy brazing and welding, corrosion resistance, but prone to corrosion cracking. 

(2) The price of Brass End Cap is cheap, and it is a common brass variety that is widely used.

2.Chemical composition of Brass Fuse Cap H65 brass :

Copper Cu: 63.5～68.0

Zinc Zn: balance

Lead Pb: ≤0.03

Phosphorus P: ≤0.01

Iron Fe: ≤0.10

Antimony Sb: ≤0.005

Bismuth Bi: ≤0.005

Note: ≤0.3 (impurities)

3.Mechanical properties of Brass Fuse Cap H65 brass:

Tensile strength σb (MPa): ≥390

Elongation δ10 (%): ≥40

4.The application of Brass End Cap H65 brass: 

H65 brass tape is mainly used in the production of electrical components, lamp caps, battery caps, buttons, seals, connectors, and is mainly used as electrical, thermal, and corrosion-resistant equipment. Such as electrical components Fuse Inner End Cap, switches, gaskets, gaskets, electrical vacuum devices, radiators, conductive base materials and automotive water tanks, heat sinks, cylinder fins and other parts like Brass Inner Cap.

This inner caps are stamped by mold with production efficiency 50-60pcs/min. These inner end caps finally are usually pickling passivation surface treatment or silver-plating or as customer’s requirement.Silver plating is generally used to enhance the electrical conductivity of caps,improve conductive contact impedance and enhance signal transmission.(Silver has the best properties, oxidizes easily and conducts electricity when oxidized).There are 9 processes in pickling: pretreatment of pickling - washing with hot water - washing with flowing water-- first step pickling - -washing with flowing water -- second step pickling - -oxidation protection agent -- washing with flowing water - -spin-drying.

We have many other kinds of T2 copper,H59 brass,H65 brass,H85 brass end terminal, Zinc-based aluminium alloy and other material for in EV/PV Fusible industry.Different size of inner caps, outer caps,L-type terminals,one-piece bolted caps, blade-shaped terminals , socket and clips etc.
